Do you have a headlight switch and a wiper switch schematic? I think I have them figured out but it would be nice to see what you did

So I have reached a bit of an issue with regards to the dome light, more specifically the door jam switch connectors. I have the wiring that came from the car but cannot ID the wires that go to the door jam switches. I ordered new switches and they have 3 round holes in the back and I cannot find anything that remotely looks like. I also located what I believe to be the original switches and one has two spade connectors and one has only one receptacle for something like a probe or bullet connector.

Any input here? Here is a pic of the door jamb switch that inline sells which I do not think it correct. Looking at various wiring diagrams, there are/were switches that had 3 connections but I do not think mine did. The second picture is what I think I need.

I think I got it figured out; I have the wrong door switches

I don't have what I did exactly, I just traced the factory harness diagrams and used an ohmmeter. I also left the wires tagged in the dash, so if I have to go in there, I know what I was thinking.

I think I got it figured out; I have the wrong door switches

I used these but from Rock Auto. Seem to work fine, but I have no factory wiring.

I dont have any factory wiring either, I do have small things and am trying to reuse connectors; meaning the factory plastic connectors which I remove the spade connectors and put new ones in. There are a few things that I haven't been able to source so I have had to reuse the factory pieces (like the 3 bullet connector blocks they used to connect things like the glove box light and the ash tray light. I am trying to find the actual bullet connectors so I dont have to reuse them.

I finished trimming up the EFI harness and got it reinstalled. Looks so much better than just leaving it as it had a lot of extra wire.

this wiring work is very tedious and slow, but it is interesting. Spent quite a lot of time wiring up my headlight switch and dimmer switch. I was able to test and confirm that I can use my original panel dimmer switch with my Speed Hut gauges.

My one issue now it the wiper switch; I know how to wire it but Ma Mopar used a 12g wire to power it and the harness I am using provides a 16g power wire. I am a bit concerned tat the wiper may draw more power than the harness manufacturer imagined, or MA Mopar used 12g because that wire ties into another line that uses 12g. Anyone got any insight, opinion, etc.?

I'm not sure off hand what it is, but testing how much current that wiper motor pulls will tell you. I have an inline ammeter that replaces a fuse, a pretty neat little tool.

I emailed the harness manufacturer and asked them. I suppose I can test the wiper motor, just have to figure out how to do it.

Ok, I heard from the harness manufacturer and they are saying that the 16g wire is good. I am going to check the fuse and see what that says.

I just discovered that Y1 has a AAR/TA fiberglass base plate for like $125... i ordered it with the seal and a new filter.
