Just about to go shopping at the local scrap yard and wan wondering if anyone had a diagram for a bench harness? Even if I knew what was needed for read, write etc I have complete 12 and 13 f150 wire diagrams from Ford so I can figure out the pinouts if I knew what I needed, I imagine I'll need the obd port and one of the PCM connectors. I figure it's just powers, grounds and canhi and can low? Also figure I'll need a switch to simulate the ignition switch?
