1970 911T Starter Wire Question

[surfdwn]

I have a 1970 911T that I have owned for 12 years. It has been undergoing a sporatic rolling restoration ever since I bought it. I have not done any major work to it for 6 years. Recently, the starter refuses to engage. I troubleshot the issue and have determined that the wire from the ignition switch to the starter solenoid has an issue. When I bought the car, I found that the ignition switch had been replaced with a generic switch and some of the wiring had been modified. The wire to the starter appears to be original. I have two questions:

1. Which wiring diagram should I be using for this car? The ignition switch wiring seems to line up with the earlier cars, but I have 18 fuses.

2. I have traced the wire through the bulkhead. Where does it run from there? Is there a starter relay somewhere?

I can always run a new wire and get the car to start, but would prefer to figure out where the issue is with the original wiring.

Thanks.

The problem is in the engine harness connector located in the engine bay. I cleaned up the pins and the starter fired for a while, and then quit again. I will have to do more digging inside the connector.

Pin 1, yellow wire is to the starter solenoid. On both 14 pin connectors at the rear fuse panel.
