Car is a 73 2.0L with stock FI. After R&R'ing the drivetrain for some much needed cleanup and hose replacement I've got a couple of questions on sensors.

1. What color is the thermo switch wire? There are two wires nearby, grey/brown and white. Just can't recall which it is. The grey/brown reaches better, but the elec. diagram shows white.

2. What is the other wire for?

3. Is the distributor air temp sensor what's called "temperature sensor I" on the electrical diagram?

Thanks

Just to close off this thread.....

The grey/brown (or white/orange, if you prefer) wire in the photo was indeed a patch for the thermo switch., grafted onto the stub of the white wire. To avoid future confusion I replaced the graft with a piece of white wire.

Unrelated, the red wire in the photo powers the AAR from the coil. While wrong, at least it's fused. The AAR is supposed to get power from the FP relay via pin 12 of the 12-pin connector on the Regulator Plate. Now I just need to find that white wire. Maybe it's the one in the photo? In any case, that's a different issue.
