From your information it sounds like the main ground is what you are after, that is the one from the battery to the block and it also might have a auxiliary lead that could go to the ECM harness, you can try to get one from a local parts store but as it is a Cadi you might be stuck going with a dealer to get one.

Right, and why didn't you have it repaired after they diagnosed the problem? Too much $$$?

If you're having cooling system issues step back a moment. Your Cadillac has a Northstar engine. They are notorious for blowing head gaskets. This is a $3,500.00+ repair to have it done correctly. Honestly it may not be worth fixing. HTH. -Jim
