2003 Dodge Ram 4x4. Is there one wire on the ingnition harness for 2003 ram that powers everything on remote start. I have 1 acc wire to the a/c swich and the spare acc to the blower wire. The blower wire to alarm does get a little warm. Is this normal. There should be 1 wire to power up on remote start correct.

Hi, It looks like I have the wireing correct then. There is no 1 wire that powers up everything correct. I just assume when you turn the key that one wire powers up dashboard. If I had to use a relay for blower how do I wire up. Thank you

SPDT Relay: PIN 87 = Fused 12 Volt Constant or PINK/Black
PIN 30 = Blower wire or D/GREEN wire
PIN 86 = 12 Volt Constant
PIN 85 = Ground while running You could also use your 2nd or 3rd Ignition wire like this:
SPDT Relay
2nd or 3rd Ignition wire from RS to PIN 86
PIN 87 = Fused 12 Volt Constant or PINK/Black
PIN 30 = Blower Wire or D/Green wire
PIN 85 = Ground ------------- MO

I read that the 507T Tilt/Motion sensor can go ff for no reason if it does have a diode on a wire

ok, I'm back for some more help. After installing my alarm/remote start, I have decided to install a power window module. I would like to be able to use the negative trunk output and the negative 3rd channel output on the remote start to roll the windows up and down. the window module has 2 wires, which are both negative inputs, to roll the windows up and down. I'm thinking that if I connect the wires this way everything will work just fine, but from past experience that doesn't always happen. please offer any insite on this issue. also, on the remote start, if a DMM is connected to the "negative output" on the remote start what should the reading be when the signal is sent from the transmitter???
