Ground wires on back of head

Ground wires on back of head
I got a used 91-92 Z28 harness and I am going through and inspecting every wire and will be fixing any issues and Tessa taping and split looming it. I found a wiring diagram and I think these 3 black/white tracer wires are grounds to the back of the head. I believe the tan wire is too. The diagram I found shows this should be on passenger side but these are definitely drivers side.
Also, that little orange wire, does anyone know what was supposed to be on that cut end?

Trace them (check continuity) to the pinout on the other end and look that location up in the diagram.

Pretty sure the tan wire isn't a ground.
Oil pressure sending unit maybe?

I thought that as well but this harness has the 3 wire Oil pressure sender. I need to find the diagram again but It showed 3 black/white wires as grounds and I think it showed a tan as "Ground reference" but I've been super sick and on meds so maybe I dreamed it haha

Re: Ground wires on back of head
I think that is the connector that interfaces with the body. Some of the wires go to the ALDL. Another wire goes to the check engine light. The stock fuel pump 12+ goes through that connector. Not sure about the "M" wire. I will have to check my 92 F-body shop manual.
Update: I checked my 92 Camaro shop manual. I think that is connector C207. Pin "M" is stated to be orange and it is listed as "Interior Lights, Underhood Light."
