ND what about a pic of what the door jam harness or at least the connectors to the switches look like. I am heading to the scrapyard right now to see if I can pick some up.
Hopefully this helps others. I went to the scrap yard and got some switches door jamb switches. Found the wires underneath the dash and ran them to the door holes got longer wire so that I could feed it through and connected them I got everything to work and I was about to put the door jamb switch in other words screw it back into the door jamb on the driver side and it blew the lights I cannot understand what it's doing now I've got no power to any of the dome lights nothing the courtesy light won't work either I had everything working just a second ago is there a separate I did notice that there was a third wire on the later model switches is that purposely made so that that has to be free grounded before anything or what now I'm not even sure what the hell was blown on this not really quite sure there's only five fuses in the box and they all look to be intact so what gives somebody come up with an answer
I picked up 2 set of drivers side(3wire) and 2 passengers side(wire). I did the passenger side first and as stated before these are self adjusting in design if they stick out what seems too far they will collapse to the depth they require once you closed the door. I learned a little trick as these came off a 92-96 f150-350s. If you are careful and place the barrel of the switch into a vise
(Careful the plunger inside need the cylinder to be intact and round to actuate) and use a long socket 1/2" worked, you can tap the knurled portion so more barrel is exposed and make it longer. Since I did not know the correct depth, I basically reset them to to where they would sit as new. I located the cut harness and added new longer wire so it was easier to snake them back into the cab. Shrink wrapped for added safety. Viola' light. Forgot to add that I added a new LED vestoon type bulb for the dome. Did not work swapped another no light. Well play with it and solved it by reversing the bulb(apparently they are directional. Nice and bright now. Ok now back to the drivers side. Wired up and tucked the extra wire did the same as the passenger side and as soon as I tried to screw the switch into the door jam I blew a fuse, fast forward 4 more fuses. I then installed a dedicated ground off the 3rd wire. Blew More fuses. So to end this dissertation, 73-79 at least, use only 2 wire on both or all 4 doors if a CrewCab. Works great. now only need to figure why under-dash courtesy lamps want to stay on constantly after I installed new bulbs.
2wire switch is what we need on our Dentsides. the 3 will blew the fuse. Even omitting the 3rd wire on that switch still blew fuses.
