I apologize about starting a new thread, but I feel that the situation has changed somewhat. I'm in the process of installing a remote start on an 01 qx4, but having problems with the starter wire.

The unit is the viper 160xv. I'm getting 12v constant over the purple and green starter wires. These should only be showing 12v when remote starting or turning key correct?

If I disconnect the large harness with the heavey gauge wires that connects to the relay pack and then check, there is no voltage over the starter wires, just over the red wires as should be. Is it possible that the relay pack is bad? Am I even on the right path here!?!? posted_image

There is a 4 pin harness with skinny wires that plugs into the relay pack. It has a pink, orange, purple and blue wire. Did you connect any of those wires to anything? Specifically...the purple wire.

I did use the purple to wire up a second starter relay. I think I have confirmed that the relay is bad though. I took the relay pack from my other car and swapped them out to test. This resolved the voltage problem over the starter wire.

So my next question is, was the relay likely bad to start or could I have fried it? Don't want to kill another if it was my error. And more important, can I buy an XCRS relay pack anywhere?

How did you wire the second starter relay?

I've probably used over 5000 relays in my life....could count on one hand the number I saw that were bad.

85 to starter wire from rs
86 to ground
87 to 2nd starter wire
30 to 12v

Even when I took this connection out of the equation, I'm still getting 12v constant over the green and purple start wires. Only when I swapped out the relay pack did it resolve that. The XCR relay pack appears to be where my problem is coming from.

You should wire it as follows:
85 to skinny purple (-) starter wire from XCR relay pack
86 to 12v
87 to 2nd starter wire
30 to 12v
