Yes, that was made from the passenger side wire. I reused everything and no issues. Bigger cable isn't needed for the stock alternator.

Fuel Pressure High!
Need more distance. Farther the better. Are you using a snubber or needle valve? If you using a needle valve you need to add a snubber. Most electric gauges have electronics to dampen the needle movement. Snubbers seem to do very well with electric gauges just make sure to buy a quality snubber like an ISSPro or Autometer that is a sintered metal snubber. The order you want is... Tap point -> Needle valve -> Snubber -> 5 foot or more of 1/8 air brake line -> sensor

Fuel Article - Low Pop Pressure and detecting it
Pop pressure of Injectors When you look at a 24V Cummins fuel injector and look at how it's designed and how it functions. The injector pintle is held shut by spring pressure. For stock injector, you need 310 bar (4,500 PSI) to make the injector open and release fuel into the cylinder. Now the bottom limit is 293 bar (4,250 PSI) below this point the automation gets poor and there is more smoke because the fuel can't be heated enough to get vapor to go BANG! As injectors start getting lower pop pressure they do flow more fuel but the droplets start getting larger. This typically creates more black smoke as well as increased fuel flow. Net problem is daily drivers end up suffering from lower MPG's from poor spray pattern or too large of droplets. How to detect low pop pressure Low pop pressure can be detected by engine load and RPM. You'll need a live data tool like an OBDLink LX or similar. Now at idle the engine load typically is in the 5% to 10% range for most injectors to hold an idle at 800 RPM's. It going to dance up and down in engine load at idle this is normal the ECM is constant commanding different values of fuel to hold the RPM as steady as possible. When pop pressure falls too low the idle RPM starts to rise. This is due to the fact it takes less pressure to lift the pintle with low pop pressure so the injection event starts a bit early and ends later. This means there is more duration of time the injector is open which will increased fuel flow at an idle state. The engine will attempt to hold the RPM at 800 RPM but when the engine load gets below about 5% it can no longer defuel anymore. The result is that the idle RPM's rise. If you seeing your hot engine idle RPM in neutral (or park) is rising above 800 RPM and never drops to 800 RPM then your injector pop pressure is most like gone too low. Why did I write this article? I see it time and time again where people make the comment of having injectors that are 100k miles and more. Claiming the engine is still running good and no issues. This is not true. Injectors will degrade over mileage. Like my stock OEM injectors worked great even with 150k miles. MPG was little off but ran great. Sent my stock injectors to Diesel Auto Power and had them tested on average they were 260 bar (3,770 PSI) over 30 bar below the minimum requirement. Even though the injectors ran fine they were worn out. Do not assume just because injectors still idle and run fine that there is nothing wrong. Pop testing I highly suggest pop testing your injectors every 100k miles I'm going to bet that 90% of them will not make the bottom limit of 293 bar. Most would rather opt for just replacing the injectors with new ones. Pop Pressures Be aware most custom built injectors are popped lower in the 300 to 305 bar range to enhance the flow of fuel. This also means the injector life span will be shortened as its only 7 to 12 bar left before it starts dropping below the minimum 293 bar range. Some members have come forward and alerted me that in a mere 28k miles have lost up to 20 bar as injectors settle and break in. This where you can monitor your engine load and idle RPM and see if the injectors and dropping out too low. Enhanced Pop pressures (Experimental) Some of the members here have made the choice of going up on pop pressures. This will enhance the atomization of the injector and increase MPG for most cases. The downside does reduce the flow rate of the injector being that the pintle lifts open later and drops close early. The flow is shortened but the spray atomization is much improved even for larger injectors. As for how much to increase the pop pressure is not known as of yet. I can say that some members have experimented with higher pop pressures above 330 bar and cold starting in cold climates was nearly impossible or not at all. The upper limit from the Dodge FSM states 327 bar. Injector Data and Pop Pressures I welcome other members data to compile a list of injectors, pop pressures, and manufacture data so we can get a better grasp of what works well. 7 x 0.010 @ 320 Bar Diesel Auto Power Injectors - So far with winter temperatures down to near zero I've not had any issues with starting. Engine load was about 13% when the injectors were new. View full Cummins article

Naw... Not as good as my 100w watt bulbs on the axle. I will upgrade them but I'm going to add floodlights in LED to the axle. Much better than the stock back up lights that doesn't work really.- Head gasket replacement
@JAG1 where does this bolt go? Clank....- Big change in my life...
After 24 hours of being home, I feel so much better. I've gotten rest and a bit more time to heal. Pain level is nice and low yet. I've got an appointment to have the tube removed from my back on Wednesday then I'll be able to wear my blue jeans again and walk normal again. More or less my biggest thing is keeping hydrated and keep flushing my kidneys and bladder good so no infection starts. Even though most are shocked at the amount of driving I do for MoparMom just getting up this morning and expecting that was relaxing in its self getting back to the normal routine.- PDC
Very good explanation...- Fuel Pressure High!
Same here. Mine are currently disconnected. Powerwise at the battery. But if you disconnect the grid heater solenoid leads yes it will throw a code.- Head gasket replacement
Same here. Timing advancement of the Edge Comp?- Fuel Pressure High!
FSM covers the VIN code and body codes and nothing listed for California I could tell.- Front end
Sorry gang... My local branch of my bank now is 125 miles away. I've got two check sitting here and got to remember to take them with me. Paypal is much much easier to handle and I don't have to drive anywhere to process paper.- Can't sleep bad ideas in my head
Entire cluster. I'm not sure how much of you can condense. It's the fact when things go missing in this CCD network weird things happen. I'm not sure how much you can remove without the CCD shutting down and quits functioning.- Budget build, need advice
Agreed the 1/2 inch has to start at the fuel tank and finish at the VP44 while keeping the stock fuel filter can.- Budget build, need advice
7 x 0.010 might overwhelm the AirDog 100. Being you get 6 PSI drop on stock injectors. The drop will just get worse with a 7 x 0.010 injectors. As for the 7 x 0.010 will end up being too smokey on a Smarty S-03 since you can't control the timing properly. Yeah, I know got setting for Mild to Wild on timing. Still doesn't allow you to adjust the way you need. Now the Quadzilla you have that control of the timing and set up fairly easy. Now with bumping the pop pressure up, I'm finding that you got to retard slightly Because the flow rate is down but the atomization is up and ignites easier.- Head gasket replacement
Yep... Gotta be with family first. More important that Cummins. Get your mind right first and the rest will fall in place, my friend.- 5 Speed Clutch Pedal Travel
I would rather reverse that around. Stay with stock hydros then use a block on top of the pedal to push the pedal to the floor. This way no worry about over adjustment. The blocked pedal still gets the pedal to the floor as needed. It could be done pretty trick by removing the rubber pedal pad and the having a slip on frame block that locks with two bolts by tension. Yeah I can see it in my mind just can't explain it well.- 5 Speed Clutch Pedal Travel
Don't use adjustable hydros. Very common for people to adjust them poorly then hyperextend the throwout bearing through the pressure plate fingers causing damage. You best off leaving the stock hydro installed but just freshen them up. I've talked to South Bend about this and the hyperextending the throwout bearing more common than you think. Typically because people buy the adjustable hydro to attempt to change where the pedal engages the clutch at. These are typically the people the end up hyperextending the throwout.- Big change in my life...
Oh my, it nice to be home. (Whew!) Finally got back to Brian's house yesterday and packed our stuff up and rolled on to get Mom from the dialysis center. I was still hurting for sure but tolerating it knowing the end goal was going to be much better. Amazing evening. I got home and struggled to get everything hauled upstairs. Started doing the normal thing of relaxing in front of the computer and taking care of the website. Happen to spot @IBMobile wife Jennifer on Facebook and for whatever reason, I called her last night. It turned into an extremely long conversation that covered herbal medicines, spiritual life and just life in general. During this conversation, it makes me so grateful for my extended internet family I've created here on the M73M website. I really do appreciate everything everyone is doing to help me through these times with my cancer issues. You all have provided me the strength to keep going through some scary times. I thank all you for just being there for me.- Rebuilding the G100 ground
Little extreme. Looks stellar for getting it all on a terminal strip. Could have just stripped all the wires, stuffed a single ring terminal and soldered the ring terminal to the wires. Then bolted back directly to the fender. The insulated terminal strip has a bad side is that now all these independent connections has full exposure to water and oxidation. It will work but comes at a price that more exposed metal to water and air will oxidize faster. This is why the factory had it all jammed in a ring terminal soldered. Less, exposed area to the elements.- Fuel Pressure High!
As for the fuel pressure sensor. My sensors is a good distance from the tap point, snubber back at the tap point. As my boost and fuel pressure are mounted on the fender forward of the ABS module. This is an ABSOLUTE NO-NO... Even if there was a snubber before it still a NO-NO. NEVER install the sensor at the VP44. The pulses are still extremely strong and ruin the fuel pressure sensors. There must be at LEAST 5 foot of tubing from the tap point and snubber to the sensor.- Head gasket replacement
Mine was a bit different no real rust but it was dark/blackish looking. Unmolested picture after the head was removed.- Front end
Then a guy like me with my stock looking truck comes along and steals your chick because I just whipped you in street race with 245's tires. Seriously, I've surprised a lot of people with my truck, the perfect street sleeper. I got it to admit it was nice to hop back in the saddle yesterday got to the I-84 kick the pig and roasted the tires in 3rd, hit 4th hopping, nailed 5th and was hitting over 80 MPH before the end of the on-ramp after being in the hospital for 3 days. There was a post back aways back... Well, yeah everyone thinks it looks cool. I do as well it does look pretty darn good. There are forces of leverage that cause huge issues with the front axles with larger tires and wheel offsets. The final gear ratio gets altered without any considerations. This why people like DOR exist is to get the parts upgrades to hold larger tires without damage. Then the gear ratio issue most dismiss but end up eating transmissions and drivelines because of the torque trapping you do with final gear ratios below 3.55. Optimal is 3.55 to 3.73 to the ground. Most add tires and end up in the 3.00 to 3.20 realm which is too low.- Budget build, need advice
Ok, being I support Smarty as well I've got to be honest and show the numbers. Now Smarty Touch and the Smart S-03 for the 24v are still only a +60HP tuner. The only Smarty tuner that can meet Quadzilla at tuneability is the Smarty Touch (or Smarty MM3) but the price on the Touch or MM3 is $1,724.00 for the complete kit getting Touch, Pyrometer probe, Dongle to unlock the software (UDC Pro software), ComMod to allow on the fly adjustments (like the Quadzilla). Now compare to Quadzilla at $675.00 it's a +180HP tuner and that covers everything you need. Pyrometer comes with the kit where Smarty Pyro is an extra cost. Custom made DAP injectors. DAP 7x0.010 injector nozzles on my stock OEM bodies. I requested 320 bar for pop pressure typically the 7 x0.010 are set for 305 bar. Keep in mind the bottom limit is 293 bar and the injector pop pressure is TOO LOW. Yeah, it does allow more fuel flow but the automation efficiency is lost. Then longevity is lost too because the injector will settle out about 10 bar in the first 10k to 20m miles. The extra pressure give more mileage to the longevity and efficiency like my 7 x 0.0085 injectors @ 305 bar didn't even make a full 100k miles around 70k miles and the MPG fell off. Keep in mind stock pop pressure is 310 bar. - LED lighting - Exterior lighting
