How to ground PDC?
This entire time I’ve been reading the title of the thread wrong. I read PDC as PCM, (powertrain control module, aka ECU). The PDC (power distribution center) is not externally grounded per se, all of the sensor ground and relay grounds are ganged in to JC-1 connector and must be routed to ground. At least in my 01 ram OBD2 PDC that’s what it’s labled as. Grounds will be black or black w/blue tracer. 97 may be different. Pic attached and JC-1 circled in red. I tied all of mine together and ran a dedicated 10ga ground direct to battery negative. Sorry for my confusion.
