GOT2B GM Posted September 26, 2006 Report Posted September 26, 2006 look for a white tach signal wire behind the gauge cluster Quote
turbogp218 Posted September 26, 2006 Author Report Posted September 26, 2006 thanks for the info on the wire behind the cluster. And obviously it is not a tgp i asked in here because people in here know what they are talking about it is on my friends car Quote
Pontiac6KSTEAWD Posted September 29, 2006 Report Posted September 29, 2006 Going to be doing something like this to my TGP since I have dualing guages. Is there a way to access the white wire without pulling the cluster and dash pad? I want to wire mine in with a harness that I can take out when not racing. Quote
GOT2B GM Posted September 29, 2006 Report Posted September 29, 2006 You could probably tap into a tach signal at the firewall connector or at the ICM. Quote
GutlessSupreme Posted September 29, 2006 Report Posted September 29, 2006 You could probably tap into a tach signal at the firewall connector or at the ICM. Possibly even at the OBD 1 connector. Pretty sure you can get the signal from there. Quote
