I'm looking for some help with an electrical diagram for the pigtail connectors in the passenger side lower cowl area for a 1991 Ford Bronco.
I have a 1991 with 1992-96 doors. There is a gray pigtail connector coming from the passenger door (92-96) that has 4 wires. Two of the wires (W/LG and DG/O) are for the passenger door speaker. The other two (BK and BK/BL) are for the courtesy door light. They connect into a gray pigtail connector coming from the cab that has a 8 pin connector (C209) with 7 wires - one slot is left empty. Two of the wires are hot all the time (BK/LTBL and BK/W). The rest of the wires are as follows; RD/W, W/P, BL, LTBL, BK. I am trying to find a diagram of the 8 pin connector (C209) coming from the cab with the 7 wires. Any help or photos would be appreciated. I am trying to determine what the harness from the cab side powers. It doesn't seem to match up to the door plug. Please see photos below.

Here is a better description of the 1991 harness/connector in question. I am trying to find a diagram or description of what this connector powers/controls. This is an 8 pin connector with 7 wires connected. Any insight you can share is much appreciated.

@miesk5 Hey Brother, do you have anything in your chest of treasures on this?

Does anyone have a photo of the wiring behind the passenger side kick panel cowl on a 1991 Ford Bronco Eddie Bauer?
Here is my problem. The wiring harness I have is a Frankenstein between a 1995 door and a 1991 cab harness. I can't tell what is original to the 1991.
I went to the junk yard today and looked at harnesses for the 92-96 but could not find any 88-91 Bronco connectors. The connector in question for me is the Gray 8 pin connector above. It has power and ground so I am assuming it powered some accessory, maybe an option. I can't find a diagram for this connector anywhere. It looks like on the 88-91 the speaker connector was a separate 2 pin connector and the power windows and locks were from the green connector. On the 92-96 the Black connector was the power windows and locks and the gray connector (8pin) was for the courtesy door light and speaker (2 sets of wires for each). I can simply leave the connector unplugged but it would be really nice to know what these power leads are for and how I can tap into them for other accessories if needed. Again, if anyone can provide a photo or diagram of the lower passenger kick panel connectors on a 1991 Ford Bronco EB it would be greatly appreciated. Otherwise I guess I will have to chase the wires down the harness to see where they go.

With much appreciated help from @Festus and @miesk5 I was able to determine that the wire harness in question is a connector to the OPTIONAL electronic shift control module for electronic 4x4 engage. My 1991 Ford Bronco EB has the manual shift on the floor so did not use this harness/module. It must of dropped down after I did my 92-96 door swap causing me to believe I had a loose connector. However I did find out that it has a couple live wires and a ACC wire I could tap into in the future for an accessory if needed. Anyways for prosperity reasons and to help anyone else out in the future that might run into this, I have the attached photo with call outs of what I was able to figure out. Thanks again for the help.
