I have a complete Zex system that I removed from my C6 before I traded it in on a 19 GS last year. I'd like to use the same system on my LT1. I don't see why it won't work the same way it did on my C6. My only question is what color wire do I tap into for the TPS trigger? Thanks for the help....

There are 2 TPS signal wires, one dark blue, the other pink. One is rising and the other, falling. Choose which operation you want (rising or falling) and properly connect to it (no "T" taps or scotch lock garbage) to your controller.

Cool. Thank you. I believe I need the rising. The solenoid operates at 5 volts. Sounds like I need the dark blue. Soldered joint and all. No taps. Got it.
