OBDII port

I have a 2000 truck harness and PCM. I'm trying to figure out which wires to tap into for the OBDII port. since the engine harness doesn't have the actualy port wired into it, I'd rather just wire one in than finding the body control module's harness and wiring it into that. I'm sure it isn't hard, I've been trying to find a few wiring diagrams but have had no luck so far. I am this weekend going to the salvage yard to pick a OBDII port from a 99-03 truck so it'll be compatible.

thanks for the help.

you need to add a wire from pin #58 of the blue connector for the OBD2 port connection.

The obd 2 connectors are all the same as long as they are from 96 up.

The Connector is numbered on the outside edge. 2 is Obd2 diagnostic from pin 58 on your pcm. 4 and 5 are ground to frame. and 16 is all time battery power.

I haven't seen one as yet, but that #3 tan PCM wire has to go somewhere.
