wondered if anybody on here would happen to have a wiring diagram for 389 and 379 headlights, I've got a set of 389 headlights im putting on my 379 Pete, wires are different though so I thought I better get some better advice before cutting and splicing!! LOL!! Thanks

Minimal amount of wires there buddy. Try a test light.

Works fine for the 379 side, test lights don't work on wires without power though, I need the 389 side
-
Took the light apart on the 389 and figured out the lighting circuit, here's the hookup for a 379 if anybody else needs a quick reference. Since all I got was ######## answers on here!!
