Never mind fooling with the unknown and make up your own wire harness; that will take the guess work out of what color wire goes to what. The article below may help you make a harness. @dripleyI've been in JAG1's driveway for the past 10 days redoing the roof on my 5er with him while I redid his heater core and AC evaporator in his work truck. He has wifi but where I'm located on the driveway it is really slow.

Write what your going to get on the back of your hand next time. For lighting you can get power from the blub for the ash tray. You can run all the wiring through the rubber grommet on the left side of the fire wall. A few extra feet of wire for some applications but no drilling, no rust.

This is true. People have to evaluate the condition of their HVAC box and ability to perform the task then take action accordingly. For some trucks, the driveway queens, just pulling the heat core is all that is needed. Trucks that are in forest or farm conditions all the time will most likely need a complete remove, clean, and refit. Yes, I remember @flagmanruss. He lived out in the woods of Coventry, RI,

@JAG1 and I pulled the HVAC box this past week. What a PIA. Your evaporator doesn't look that bad. The evaporator was blocked about 15%, not real bad. If all you need to replace is the heater core then just replace that with a core that has swivel tubes, that's what we used, then clean the evaporator, ,install those Genos cabin filters like @Tractorman posted and call it good.

From the FSM is for check engine light and trouble code (P code) self erasure with 40 drive cycles. Now the condition the OP and I are addressing is resetting the monitors not erasing the p codes.

This show the voltage and amperage on the blue wire from the PCM to the alternator at idle with the headlights on with high beam, the heater fan on high speed, and radio playing; that's a 4.5 amp power draw. If the load on the alternator load increase there is a chance the 5 amp fuse will blow so I sized mine to 7.5 amp.

Before having the the state mandated emission test performed 0n my truck I've reset the monitors with 3 drive cycles after clearing a P code. This has been done several times over the years.

3 times, starting with engine temp below 160°, for 20 miles miles each should reset the monitors.

I've got my 5th wheel set up in @JAG1 driveway today and will be pulling his HVAC unit out tomorrow to do both heater core and AC evaporator, both are leaking. We'll see how it goes. I have replaced the heater core in another truck using the "short cut method" but that was a few years ago and the truck had low mileage' i used a heater core with swivel pipes and it was not a hard job. Still no leaks to this day.

P0172 Fuel System Rich Bank 1. O2 sensor is most likely seeing a lean condition and the PCM has richened the mixture as far as it can and is out of set parameters. With the vehicle less than 5 years old and under 50,000 miles the factory emissions warranty should cover the repair. Go on line and find out what the emissions warranty is on the vehicle.

@JAG1 order it now and it will be there Friday when I put the box back together. http://heatertreater.net/dodge-ram-95-02

Yes, I've done it to bleed the system when MoparMan and I replaced the injection pump, when I've replaced fuel filters, and when replacing injectors.

If you have the relay wired with the ECM triggering it then you can get the fuel pump to run without bumping the ignition/starter. You can remove the relay and put a jumper wire between terminals 30 and 87 in the plug; as long as that jumper wire is there the fuel pump will run.

I always use terminal 85 as my ground, black/white wire, that's the way it is on most wire diagrams. Terminal 86 is ECM ,use yellow/white wire, switched and only needs a 2amp fuse if you want too add one there. That relay you are showing does not have surge protecting with a resister or diode. This is important to keep voltage spikes traveling back to the ECM when the relay is shut off. I've seen spikes as high as 100 volts dc from an unprotected relay. Try to find a switched 12 volt feed in the PDC and use that as your 12 volt supply within line fuse to terminal 30. Yes, 87 to the fuel pump.

I have to agree with @01cummins4ever. I have a California class A CDL and tow doubles. Your looking for trouble towing a vehicle that heavy behind that trailer. .You will be going to NY on Interstate 80 or 90, When you get to Illinois the toll roads start and the tolls are really high when there is more than 2 axles. Also those states and toll roads may not allow double towing in that configuration . Some states require a CDL to tow doubles. Try to find a different way to do this move.

That's about the right price. I checked on about 10 different evaporators. The price range was $30-$75. I'll also replace the AC accumulator and orifice tube/high pressure liquid line and add 4ozs of PAG 100, As for JAG1, he lost that screw a long time ago.

Wire your relay like this.

All you have to do is look at what was normal before 9/11 and what liberties we gave up to the government after in the name of antiterrorism. People born just before 2001 and on think of what we have now as "normal". We are witnessing the genesis of another new "normal" as the government social engineers in the name of citizen safety. "Never let a crisis go to waste."

My spring fishing trip has been cancelled when CA Fish and Game moved the season opener from the last weekend in April to June 1st. I'll be doing other things. State, Fed, and most private campgrounds are all closed here. The private campgrounds that are open in CA depends on which county they are in.

You might want to install a filter in the return line between the steering box and pump.

She could do us all a BIG favor if she just would stay in her kitchen with her $24,000 refrigerator/freezer full of ice cream.

Even a paper bag with eye holes couldn't help her. "Let them eat ice cream"

ECM, Engine Control Module, located on the left (driver) side of engine. PCM, Powertrain Control Module, located on the right (passenger) out side fire wall.

P0920 Gear Shift Forward Actuator Circuit/Open P0921 Gear Shift Forward Actuator Circuit Range/Performance P0999 Shift Solenoid "F" Control Circuit High None of the above codes pertain to your truck, don't know way they would be coming up but they can be generated from the PCM. P1389 No Auto Shutdown Relay Voltage At Powertrain Control Module You may have a problem with the ASD relay circuit, power going through the complete circuit or the PCM is not grounding the relay for some reason. See below for test instructions. The batteries going dead after sitting unused that long, new or not, will go dead.
