question about meth install
Hi, I have removed a alkycontroll kit from a 02 zo6 and am installing it on a 05 C6. I have all of it done except for one wire. The green trigger wire that goes to the map sensor.
On the 02Z it was ran to a wire on the ECM, not a map sensor like the kit supplies. Is this doable on the C6? Anyone know which wire it would hook up to on the c6 ECM?

Sounds like the installer might have used the factory MAP wire. The C6 has a MAP sensor, so if the input impedance is high enough on the Alky kit to not interfere with the MAP signal going to the PCM, I don't see any reason you can't wire it up the same way.

Ya thats exactly what the installer did. Now anyone know where the wire is on the C6 ECU?

Try grabbing it in the harness closer to the MAP. You have a 5v supply, ground and your output, which I believe is in the middle. Use a DMM to verify. It will be ~.5v at idle and 4.7V+ at WOT. Once you verify its color, you can chase it back to the PCM if you care to.
