WTB 1975 dodge van underhood harness
probably could source that for you in the ep tx u pull it yard i frequent.
you didn't specify engine / trans combo, air conditioning or transistorized igniton - being 75 would assume yes. I don't know when dodge introduced "modern" vans - such as 71 for chevy and 75 for ford. So there must be some type of interchangability - 73 to 80 perhaps??
