I have a OBD2 to OBD1 conversion harness. I got it off of my friend who was an idiot and cut 2 of the wires on the harness. 1 Of the 4 Ends (2 cut wires) I cant find, and the other 3 are visible. Does anyone have a schematic to show how the wiring of the OBD2 to OBD1 conversion harness so I can repair it. I belive he cut the ones for the O2 Sensors if thats of any help.

if you cant find the diagram for the conversion harness. you can just find the pinout of the harness you are using, than find the pinout of the ecu you are using, find the pin connectors that are missing and reference them to that so you know which wires are not being sent to the ecu. if you need help, post what harness your using, what ecu and year you have.
