For reference, this is a1991, D90, 200TDI, HT from Italy. Any help is appreciated, thanks in advance.
Peeled apart the Gauges today so I could put the SHP Aluminum binnacle mount in while waiting for some gaskets. Found some minor gremlins in the wiring, and some random thing I have no idea what it's for.
Puzzle #1
Harness PRC8410 is in question. All the illumination wires were cut out of both sides of the plug for whatever reason. So what I am guessing is the illum wire (white/red) were all splices together, and connected to a larger awg red wire that had a fuse tube. Doubt that fuse is factory but maybe. Fuse holder and new illum wires circled in red. The screw down connector is how they connect to the illum wires now.OE harness and where they cut them in blue. Trying to figure where the white/red that came from vehicle side harness went. Was the fuse holder in play prior to whatever engineering took place here
Puzzle #2
On the gauge side of the harness, i found about a 2" wide piece of foam tape wrapping up a small device and secured the excess wire via ty-wraps. The grey foam tape had the worlds most stickiest adhesive, and was a mess pulling apart. Looks like there was a ground, 2x green/black, and a white/black wire attached. Both green/black came from the same harness circled in blue above. you can see the two wire at the bottom of the pic. The 3 in tape are the gauge feed wires. Im almost certain that the white/black had a female bullet on the end of it, connected to nothing. Any clue what this is?
Extra Credit Puzzle - Unused connectors.
Anyone know what options these are?
