Help identifying wiring in engine compartment

[coolcolger]

Good day,
trying to get back into the Volkswagen way of life after being away for ten years or so. I have gotten back around to working on my 76 bay and now being more mature than 16 year old me I would like to set things right with my bus. Long story short, my 76 started its life with a 2.0 liter fuel injected engine and it has what I believe to be a 1.8l type iv from a late 70s 914 as the oil fill and dip stick are on top of the engine. The engine now has dual weber carbs. I have never had any working instrumentation at all other than the high beam indicator, the turn signal indicator, and a voltmeter that was added to the empty right most gauge spot. In a perfect world I would like to get everything applicable working in the cluster. I have a speedo cable on the way to delete the "inline emissions box" and hopefully get the speedo and odo working again. On to the question: I have some wiring in the engine compartment that I imagine to be related to instrumentation just loose or clipped from my botched engine swap years ago. I have attached images. The first being two/three wires being fed into the compartment from the passenger side, one wire just being black, the other being two wires crimped together turquoise in color with maybe a black stripe. The second image is on the driver's side, one just a black wire and the other red with white stripe. Lastly in the third image is a wire with a large plastic case on the end with blade connections that is coming from the same harness with other wires running to the coil, it appears to be green/red in color with black stripes. Any ideas guys? Any other tips to setting my wiring/cluster straight would be greatly appreciated. Thank you!

Hello,
It looks like you have a date coming up with the color coded wiring diagram in the Bentley Manual.....Study it well. All your answers could be found there...
Oh, and nice gloves....

clean the wires with a small amount of carb cleaner on a rag to see the real color. Then look on the wiring diagram to see what wires are that color. Use a volt meter to verify what's at the other end.

I can tell you that the turquoise wire was certainly some kind of PO addition/hack/repair.

By the time your bus was made, the wires that had a stripe, all had the stripe running in line.

That does sort of remind me of my 1960 Beetle's wiring but I can't say for sure.

My guess is a PO used a scrap of wire that they had laying around for whatever that one is doing.

I am going to guess your dealer diagnostic plug has been removed and some of the cut wires were for that.

Black---#15 ignition circuit

Red/Wht---either the #30 (B+) circuit or the #50 from the starter to the double relay.

Does your oil pressure warning light work? It should be a blue/brown wire

Double blue wires in the first picture go to the Voltage Regulator wiring harness
