'83 Glow Plug Controller Quesiton

I'm almost done with my wiring harness restoration (praise baby jesus), but I have a question about the pinout for the "old-style" cylindrical '83 glow plug controller. I have all the wiring for it worked out, except for one mystery wire that has been cut. On all of the diagrams I've looked at, the pin the I have a wire coming out of, the diagram shows nothing there. Please advise.

In the image below, you will notice that the #2 pin has no wire coming from it. However, mine has a tan wire coming out of it, but it has been cut.

P.S. - It may be helpful to know that the previous owner had the glow plug override switch for manual glow operation installed.

Hey man look, I obviously don't understand the schematic because the one I have has no wire coming out of where my actual controller does have a wire coming out. I started this post hoping that someone with more knowledge than myself could chime in on the matter. It shouldn't be this hard to ask for help.

If you would have gone past the schematic the answer is there.

PIN 2: There is no connection to this pin on 1982 vehicles. On 1983-84 vehicles, there may be a white tube or a wire
to this pin, it is only to seal the position in the connector. It is hooked to the wiring harness. DO NOT GROUND
THIS PIN FOR ANY REASON, IT WILL PROHIBIT NORMAL OPERATION OF THE CONTROLLER AND CAN
DAMAGE GLOW PLUGS.

This help you figure it out?

Yes, thank you that's what i'm looking for. I don't have my PDFs because I'm on a school computer in a university library. I tried searching online, but couldn't find anything and I can't download new PDFs to these computers. I do appreciate your help, though, including all of my past wiring posts.

If you still help with tracing wires my K20 harness is pretty much intact, but I wouldn't be able to look till next weekend.
