2005 E40 ECM Pinout
Anyone have a pinout for the E40 ECM on my 2005 corvette? Specifically the C3 gray plug on the top? I pinned the ECU for flex fuel and want to double check my work as I started the car last night and dash is reading "oil pressure XXX". Want to double check that is is not affected by that connector.

I only have the 2006/2007Service manual, and thus I'm not sure if the pinouts are the same. I have attached the 2007 ECM connectors/pinouts. The ECM C2 connectors shows it as GY, so I've attached it. You can have a look to see if it is like yours.

It's possible that the oil pressure sensor went bad. A thread on here yesterday asking how to get to it to replace.

Mine says "oil pressure XXX" which i believe means there is no signal at all from the sensor. Same thing happened when i did my cam swap on my z06 a few years ago and bumped the sensor off re-installing my intake manifold. If there really was no oil pressure Im sure it would read "oil pressure 0psi" and I would have a very loud valvetrain haha
