The C5 does not have an ECU but I believe that you need the PCM ground locations
The Power Train Control Module (PCM) ground is located at ground location G-106 which is located on the engine block just above and fwd of the starter. It is a bitch to get to especially with headers!
There are 4 PCM ground wires that all tie together and ground at G106.
They are Connector C1, pins 72 & 76, Connector C2, pins 21 & 66
If you are talking about the Body Control Module, Please let me know and I will look that up also. There are a lot more grounds for that beast!
The main BCM ground is G-104 which is on the top of the passengers frame rail inboard of the battery.
