Hello,

I am planning to install an add on remote starter in a 95 or 96 (can't remember) Impala SS. It has the vats security system on it. I was planning to use a relay and resistors. I know to check the resistance of the key. My question is in wiring the relay. Ok, here's what I got:

85 - remote start output

86 - 12v

87a - switch side of vats wire

30 - starter side side of vats wire

87 - ?

I know i need to put the resistor on the 87 pin. The only thing I was wondering is if it's resistance to ground or 12v? How do I wire pin 87?

Also does anybody know what color the vats wire is in this vehicle.

Thanks.

85 : GROUND OUT WHEN RUNNING WIRE from alarm
87 : Uncut wire from the two VATS wires with resistor pellet
86 : Primary Ignition ( NOT CONSTANT )
30 : Keyside of VATS wire
87a: Computerside of VATS wire

Here's the diagram if you need more help: https://www.the12volt.com/uploads/files/GMVatsPassKey.gif
