Gentlemen, I need your expert help.
I purchased a M151a1 (AMC March 1965) three months ago and had been working on the body replacing bad areas of rust, priming and painting. The engine runs good, but the Mutt came without the original light switch and ignition on/off switch. All the wires had been cut to the switches and to the tail lights. It had an automotive light and keyed ignition switch witch I wanted to replace with originals. The guy I bought it from had a new front and rear wiring harness still in the package, so I wasn't concerned.
When I finally got around to taking out the old front harness I found that things were not the same on the new one.
1) The turn signal circuit on my old harness was separate from the main harness attaching to the front harness via six plugs. It attached to the flashing unit via a screw on plug. The new harness had the turn signal circuit as part of the main harness and a small single rubber plug going to a flasher.
2) My old harness had a large oil sending unit plug connecting next to the oil filter. The new harness has none.
3) The old stop light plug is rubber and the new one is screw on.
4) The old #5 wire to the regulator is a large screw on type and the new harness just has a thick wire that attaches to the regulator with a nut like a battery terminal, only my Delco Remy regulator has no stud for the connection.
When you have time could you experts please look at my pictures (I hope I can figure out how to load the pictures) and try and determine what I had, what I have now, and if it is the wrong harness or is it a newer replacement that needs modification. HELP me please; this is my first try at restoring a military vehicle.
