There are wiring diagrams I viewed thru Keith Hardy's Online Manuals website. 37 truck shows no terminal block or connector analogous with the terminal block in function. Don't see a connector.
38 has no truck diagram but has car, it shows a terminal block. A terminal block is not analogous to a connector. The diagram shows two wires entering from the back and one from the side. Don't see a connector.
39 truck shows no terminal block. Don't see a connector.
If you are saying that there is a three pin connector somewhere. I would love to see it. I apologize to Chasz for thinking he meant the bulb. I do not doubt you but If I don't see it, I can't learn what is wrong with my post. Especially if it is the only thing you say is incorrect. I am your friend and a friend of knowledge. If you can drive over here, you can take some pics and post them. I'm in lockdown man.
I think I understand that you guys have a genuine connector with three wires, for each can. This connector is before you get to the bulb contact housing shown in Yar's pics and Chasz says it's a bayonet connection. He says "three pin" as in three contact connector. I will wait for a pic or two.
Chasz will get it wired. It's all good. We will sort the rest out someday.
