83 911 SC / Identifying wires

[anniqu]

Hello
I have a 1983 SC ,
1) I am trying to identify where this unconnected wire is supposed to be at connected to .



2) I am trying to remove the CDI bracket but the nut just keeps spinning. What is the trick to getting it off?

That harness was used for voltage regulator. Someone must have replaced your alternator in the past. The regulator is internal on the newer models. As for the bolt look inside the fender over the tire the nut will be there.

Colors aren't quite right for the external VR - the cars which had it had brown, black, and blue wires to the 3 pin connector. But no '83 came with an external VR. You should be able to trace it to where it originates.

How far are you going with removing/taking apart things back there?

I have had this car for a a number of year and have never done it right, My conscience finally got to me and I am going all in to make it proud of me. LOL .

In the process of changing out the fuel filter and accumulator. Have a rebuilt CDI to install. I guess it's time to ask it the CDI just plug and play ??

Next up
- removed fuel tank and cleaning it out
-new fuel pump
- new fuel lines
- New shocks all around
- new suspension bushings
- new master brake cylinder
- new tie rod ends
- new ball joints
- new convertible cover
- new window and door rubber
- new torsion bar bushings

CDI units have no software programming. Same as a light bulb, so to speak. They have a fair amount of electronics inside, some of which can go bad over the years, and which can be replaced or even upgraded to perform the same function. But ready to go right out of the box. No chip, no flash, no OBD, no CAN bus.
