2003 Dodge Ram, Remote Start, No Air Condition

i installed a CM900S compustar, remote start works, blower turns on after a few seconds but the compressor clutch or AC doesnt turn on to cool the air down. If i remote start it, then insert key and turn to Run, then AC and clutch engage and cools down. So do i send Accessory voltage to the Run wire of the Key switch? and which wire is the Run wire? Thanks

Have you checked the vehicle wiring section of this site? You can see your vehicle is listed as having 2 ignition wires and 2 accessory wires. All 4 should be powered during remote start: https://www.the12volt.com/installbay/forum_posts.asp?tid=3971&tpn=1

i will check when i get home. i do have accessory to the Blue wire and the Black/White wire. Not sure on Green wire or Orange wire. Is this where i should add two relays to seperate the wiring? or wire the accessory power from the cm900 to all four wires? |        ACCESSORY|green & orange      |+ |ignition harness            | | SECOND ACCESSORY|blue & blk/wht *7   |+ |ignition harnes

Yes, relays would be the way to go. Using an OP500, you could reprogram a couple POCs as negative accessory and ignition. Then use those to trigger your relays.

i found the orange wire missing accessory voltage and now everything is working. i didnt have relays but added a fuse there seperated from the other 15 amp fuse. thanks for the help.
