Yes ET, I traced the wiring further upstream of the harness and found the splice. From there, I’ll isolate & mark the 3 spliced ones & wire to pins accordingly. Then, it’s obvious w the other 3.
Question, do the connectors play a role for something else other than supplying current to headlights? If not, i could just remove connector on headlight and barrel connect them, or do as you said and install terminals and slide into connector, then wrap securely w e-tape and gorilla tape or something. Either way, I’m going to be adding some mint oil to the whole harness.
