. . Ok, , I have a '68 Parisienne 2+2. . 327 engine. . When I bought the car the temperature idiot light did not work. . Come to find out the temp sending unit did not have a wire running to it. . A quick check around failed to find it. . I thought when I pulled the engine for rebuild I would find it. . No luck. . Can not find anything that resembles a broken wire coming from any of the wire looms. . . . Any ideas where that wire is supposed to be? ?
If I recall right it should be a green wire and I think it will go to a bulkhead connector at the firewall by the brake booster. Maybe start there and see if you find a green wire there? It may have some of that braided type of insulation over it.

Do you have a service manual for your car? It'll have a wiring diagram which should show where it goes through the bulkhead. Where is the sensor? Drivers side head? Passenger side head? Intake manifold? As Carl indicates, it should likely be a green wire, and if I recall the sensor is on the intake manifold. You may need to peel a little of the loom wrapping near the wiper motor to see what you can find.
That's where it was on my 70, however I know they had moved it around a bit. So, the headlight harness should have a braided cover that splits out about midway along the drivers fender. It will run down towards the sending unit in the cylinder head, and have a green wire inside it. Is the braided cover present? If so, you may need to peel it back a bit to find the green wire.
Yours looks a little different from mine. . My alternator plug has two wires while yours only has one. . To make matters worse, , I'm color blind. . Of the three wires going to the alternator, one large looks red, one medium looks blue and the small one I can not tell. . The small one goes to the side of the plug marked R . .
. . I think that's it. . Best guess would be that something happened to the green wire and someone thought it went to the alt. . Next question would be why didn't something melt down when the green wire was hooked into the alt ? ?
