OK,
So I just bought a 73 Opel GT last week for $300!!! Body is in very good condition, and the interior is somewhat there. The dash is junk, and everything but the instrument cluster was pulled out from the previous owner. I am now trying to put it all together. Never owned one, never looked at one before, but man am I getting to know it!! Car sat for around 2 years. Took me about an hour to get it some what running. The next day I went and drained the fuel system, put on new lines and a new fuel pump. Car starts and runs ok. Feels like it needs a new carb job and gasket. But now I am onto the electrical system . I am defiantly new to electrical!! I have it some what figured out ( ok not really ) but am stumped. Got the head lights working, oil light, amp light, fuel gauge, temp gauge and clock working. Still working on the running lights and instrument lights as well as the heater fan, tach, spedo, amp gauge, and oil gauge.
Questions:
1. How do you turn on the instrument lights?
2. How do you turn on the running lights?
3. There is a black/white/red (one wire) wire going to a point on the blower on the right side. Found out it links to the fan switch on the dash. There is also a black wire right next to it that also goes to the switch. I am not getting power to my instrument lights or that blower motor. I tested them and they work, but can’t seem to trace where they get there power from. I am getting power to the wiper switch, and the work! I am assuming all the grey wires for the instrument lights go to one point. But don’t know where that point is.

Any thoughts. Thanks
