remote start, 04 dodge ram

didn't you post this in car security fourum, velocity gave a diagram that you could use, let me simplify for you, on a single pole double throw relay, (the one you need for this application), the pins on the relay wil be numbered, exclude pin 87a for this application,

pin 30- goes to constant 12 volts

pin 85- goes to the ground while running wire of the remote start or you can ground it if this would be simpler

pin 86- goes to your first accesory wire of the unit, just splice into the wire, leave the unit's accesory output connected to the first accesory wire, you don't need two relays, as you were trying to find out in your original post.

pin 87- goes to your second accesory wire

THis is what you need to do:

87 & 85 - Goes to 1st ACC wire

86 - Ground when running or if the unit has a designated (-) 2nd ACC output wire

30 - goes to 2nd ACC wire

87a - NOT USED
