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

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