LS1 Camaro SS ECU Pinout & wiring help

[Blacksupra93]

Hey everyone,

I'm trying to figure out some things about various guage installs on a 2000 camaro SS. It's been converted to turbo, but the guages are being erradic, and I'm not sure the air fuel guage is working correctly. I was hoping someone has some wiring diagrams for under the hood and also an ecu pinout diagram.


The guages don't always come on when the key is turned to on, and then will come on randomly. I'm thinking maybe a loose connection or its tapped into the wrong wires.


and also there is a red wire that is going into the alternator on the passenger side. It seems that whoever did the isntall tapped into a red wire that comes off the harness over by the TPS wires, and ran it over to the alternator. Not sure if it's supposed to be there or what the purpose is. It's just sitting across the top of the engine now.

I know its hard to troubleshoot without pics for wires like this, but if anyone has ideas or wiring diagrams that'd be great.

Thanks
