Hello, looking for help on where to pull my 12V ignition power from for my isspro gauges. I am planning on daisy chaining all 3 gauges together. It comes with a supplied 1 amp fuse, but would I need a larger fuse if daisy chaining all 3 gauges together? Or will the 1 amp fuse still suffice? I have read a lot of stuff and everybody seems to be doing it their own way, or different ways at least. My plan is to pull keyed power and run an in-line fuse. Thanks in advance for the help. Wiring is not something I am great at. 

No. 1 amp fuse is cover all 4 of my gaugss.

 

I picked a fuse that was key on for switched power.

Thanks. I probed the #15 fuse which is the 20A cigar lt fuse and got 12v key on. Can I simply use the add a circuit fuse holder to that location or would it be best to find that wire and splice into it, then add my inline fuse?

I think when I added my gauges I went off the fuse for the radio.  Pull the fuse add in one of the fuse taps with your fuse for the gauges and put the original in it too, wire in all the gauges into the fuse tap and your are good to go.

Thanks HD. From what I was reading it seems like most people make it quite complicated and wanted to make sure I wasn’t oversimplifying it. I will daisy chain my gauges together so it will be 1 wire for ignition, ground and my last wire going to my dimmer switch wire. I will use the cig lighter spot for now. Unless charging my phone and using my gauges at the same time blows a fuse. I might try the radio then. I appreciate the help.

I don't think that will be a problem.  Most chargers are only 2-5 amps and this would be a 20A.

I installed my gauges and they are up and running. Just curious with my pyrometer, is it supposed to zero out at shutoff or does it remain at your last reading? Right now it is sitting at 350 with the truck shut off. Also, I couldn’t find a 1 amp mini fuse so I am running a 2 amp mini fuse. They are the smallest oreillys had in stock. The directions say 1 amp should be used even if daisy chaining gauges together. Also, I am still waiting on my fuel pressure gauge to show up, going electric.

Remains with the last reading. 

 

If you want send me your gauge I can program the warning light for any temp, pressure, etc. Or just pick up the EV2 programming cable its like $27 bucks for the programming kit.

I will likely pick the programmer up. That would be handy to have. I think I may have my egt probe a little off center as I was at 900 going 60 mph up a slight hill. I need to look up the normal numbers while cruising. Thanks for the offer on the programming.

No problem one of the many features I wanted for my gauges. Programmable warning lights. Offer is open for anyone that reads this...
