2003 dodge ram 2500 alarm/remote start

I know there is someone that knows the answer. I am sure a relay is involved to power up my A/C on the steering colum but I do not no which one, I really do not want to keep screwing with it and blow my air bag or something guys, please healp.

You should not have this wire left over. You are supposed to have hooked this wire to the second ignition wire. Failure to hook this wire up could damage your transmission. Second Ignition: red or RED / wht (+) ignition harness

Accessory: green & orange (+) ignition harness

This should be supplying +12volts while remote started. If not then you have a problem with your unit. You will not need a relay for this connection.

Thank you  iskidoo

Where you able to locate the Accessory wire? There might be Two Accessory wire. Accessory 1 and Accessory 2. You will only need to hook up the Orange wire from the remote starter unit to the Accessory 1 wire of your vehicle. You do not need a relay. You will not blow up any airbag if you are not poking at wire that has a yellow loom around it. Yellow loom around the wires are most likely the air bag wires. Your Brown wire on the remote starter unit is set to default for Second Ignition. You can connect the Brown wire to the Second Ignition wire of your vehicle. You won't need 2nd Ignition if you live in region where the climate never hit's 0 degrees. Otherwise you may use this wire as a Second Accessory wire. If you are using the Brown wire for 2nd Accessory you will need to program it for 2nd Accessory. The instruction for setting it is located on page 23 of your installation manual . It will not effect the remote start. So try powering up the 2nd Accessory. It might be what is require for turning on your AC. I live in Canada, I am only concern with powering up the heater so I really don't pay much attention to what wire is require to turn the AC on so I cannot tell you off hand. Anyways, the basic is there. So it just a matter of trial. Post your result when you are done. As for damaging the transmission for not connecting the 2nd ignition wire. That applies to GM vehicle.    Be careful whose advice you buy, but be patient with those who supply it.

I have looked up and down ignition harness. No ORANGE / green wire to be found

Which is why you have to test every wire at the ignitions harness! The wiring diagram are only correct when a professional installer reads it and not meant for DIY and weekend installer using it. TEST ALL YOUR WIRE AGAIN AT THE IGNITION HARNESS. It will behave like the note listed below. Just pretend that the wires are absent off all color. Hopefully that will help you find the correct wire. ACCESSORY This wire will test with the key switch in the accessory and run position, but never in the start position. Be careful whose advice you buy, but be patient with those who supply it.

I hooked to my big green blower motor wire in the ignition harness with the orange (+)just for blower motor to kick on, now I have that brown wire. I have a separete a/c button you push when you want a/c. It does not work when in remote start, do I get this wire and aplly my (+) brown to it?

Problem resoved, Thank you found a/c wire.
