I want to unplug the TCM and the airbag module from the wiring/control
bus. 2001 RAM, 2WD, short cab, 318 (5.2L) with upgraded interior.

There is a small plastic cover on the tranny hump under the dashboard
held with 2 screws. I take that off and there's a big connector right
there attached to something. Is that the airbag controller? If so,
then where's the tranny controller?

The HVAC cluster also has about 2 or 3 connectors (which I unplugged).

I unplugged 2 connectors on the brake unit (I take it this is the ABS
controller).

I unplugged the 3 cables going to the PCM.

I unplugged the DRL module.

I STILL GET NO BUS MESSAGE, and CCD message on the overhead console.

Where the hell else is this bus going to ?!?!?!

Does anyone know which pins on the 2 cluster connectors is this bus?

Is it 2 wires, or one?

Does it go to the ODB connector?
