    Default LBZ bench harness wiring diagram

    Hello,

    I have just about got all my parts together for building my bench harness for programming my spare ecm and tcm for my truck.

    Just seem to be having a brain fart or something as I have all the info on pin position etc and what pins require battery power and switched power, but my brain can't work out from the EFI live bench harness PDF which wires go to the OBD connector for the CAN + and Can -

    I am assuming pin 6 on the OBD connector is CAN + (EFI PDF says HI)and pin 14 is CAN - (efi pdf says LO)

    Someone just poke me with a stick and it will click

    Can+ = high, Can- = low AFAIK.

    I just used that .pdf, you should be good.
