I will search the forum for a diagram, so that I will at least know what it looks like, plus I will sound like I know what I am talking about at the shop. The forum has taught me well... lol with a big thanks to you all.
There are 3 circuit boards in there : BCM. PCM & RCM.
As you stand by the battery, the one closest to you is the BCM( Body Control Module ),
then the PCM ( Powertrain Control Module ), and last the RCM ( Relay Control Module )

All of them have tons of connector wires, but the RCM has the least.
It can be removed without disturbing the other 2.

MAKE SURE YOU DISCONNECT THE NEGATIVE BATTERY CABLE BEFORE DOING ANYTHING !!!!!!!!
