ignition 3

grymus, you should have a pink wire for primary ignition, a white wire (usually a smaller guage) for secondary ignition and an orange wire for 3rd ignition. The orange wire powers up the HVAC so you can connect it to an accessory output if you have an extra one on your module. If you don't, you'll need to wire an extra relay to power it up. I hope this helps.

here is a diagram for an ignition 3 relay configuration:

Yeah, use the relay because you really don't want independant circuits tied together permanently. Noise, spikes, and what not could interfere with more sensitive vehicle circuits if they were tied into more volatile circuits like the ignition system. Plus, Chevy isolated the circuits for one reason or another so it's just safer to maintain the integrity of the original circuit. So, go for it and get that remote start fired up!
