Cadillac 2006 CTS-V, Owner'S Manual, Page: 316 / 434

Your vehicle has a remote negative (
−
) ground
location, as shown in the illustration. It is located
between the battery and the underhood fuse block.
You should always use this remote ground
location, instead of the terminal on the battery.
Notice: If you connect a negative cable to the ECM,
ECM mounting bracket, or any cables that attach
to the ECM bracket, you may damage the ECM.
Always attach the negative cable to your vehicle’s
remote negative ground location, instead of the
ECM, ECM bracket, or any cables attached to the
ECM bracket.

CAUTION:
An electric fan can start up even when the
engine is not running and can injure you. Keep
hands, clothing and tools away from any
underhood electric fan.
