ok guys I'm attempting to make my own jumper harness, and i was wondering if anyone can help me out as far a figuring out all of the pin locations, i have most of them figured out but i really need help trying to figure the rest out! thanks for any input in advance!







p.s. this is for an obd2a ecu into an obd1 car (the engine is an h22a and ecu is a p5m)

You'll save yourself a lot of time, effort, and headaches by simply purchasing a harness. They're not very expensive, especially once you factor in the cost of the wiring, connectors, pins, solder, shrink tubing, etc.
