cobalt passlock interface

well some one asked me to post this up so here it goes

start the car with the key then...

1 find the white wire at the column as well as a white black (there are only 4 wires there so it should be easy to find) the plug is green on the cobalt. 

2cut the white wire and strip back a lil on both sides also strip away some insulation on the black white (reference ground)

4 set your meter to ohms and put one lead on the key side of the white wire and the other lead on the black white. now as you have the meter on these two wires turn the key to the crank postion and read the resistance. now find a resistor of that value.

now here is the hard part i am going to try and explain how to wire the relays.... you need two relays, a resistor   here it goes...

12v start output from remote start (r/s) goes to pin 85

negative when remote start goes to pin 86

one side of the resistor goes to the black white wire and the other side goes to pin 87

pin 87 a goes to the white black as well (do not  put this directly to pin 87 it must not pass thru the resistor )

pin 30 goes to pin 87 of the other relay

pin 87a goes to key side of the white wire

pin 30 goes to other side of the white wire

pin 85 goes to ground when remote started .
