I was staring at the rats nest of wiring that was handed to me when I bought the donor engine I'm gonna use for my conversion. They guy said he took the entire harness from the engine compartment and boy,,, he wasn't kidding. Even the light wiring that's woven into the harness was there. Then as I was having an aneurism trying to figure out how I'm gonna do this I realized a vital part was missing. The OBD II connector.
Can I grab any connector off of say an s-10 or Malibu etc... Or do I need a vehicle specific one.
Thanks in advance.
