This is kinda long-winded, so bear with me. Thanks in advance for any input.
On my 85 Capri RS, there is a white wire with pink dots that is connected to the ignition switch wiring harness. The insulation on this wire has melted along its full length. I've traced it through the wiring harness (dash is out) and it goes to a connector at the transmission tunnel. The wire on the other side of the white/pink wire changes to tan, and it goes to a connector on the transmission's backup light switch. The connector at this location includes a shorting wire, where it transitions the tan wire to red with a blue stripe. In this particular car, that harness/plug to the back up light switch is missing (I have a separate harness out of an 85 GT that I can use to compare).
I did not find an obvious short location for the white/pink wire, although other wires have damaged insulation at the ignition switch harness. The tan wire at the trans tunnel connector is fine.
BUT - the previous owner spliced a separate red wire to the white/pink wire at the ignition switch harness and ran it to the starter solenoid. This particular solenoid has two wire terminals (as opposed to the one terminal on the OEM style solenoid). See photo. What does separate wire achieve? I can't figure it out in my head.
