73 Wiring Question
My 73 454 / AC has a loose green wire on the passenger side on the engine compartment. Picture 1 shows where the 2 wires connect together (left arrow), with the loose end being more towards the front of the car (right arrow). The 2nd picture shows a sending unit, which is under the air injection tube, with a short wire going from one terminal to the other. Does the loose end go to one of the sending unit connectors? Or somewhere else. Thanks in advance to anyone providing a little insight.

As stated the link doesn't work.
See if the A/C compressor has a wire on it- that sounds like the power wire.
the loose end being more towards the front of the car.

The link is still bad...
If the wire is green, it's probably either the a/c compressor wire if it's up near the compressor, otherwise, there's a good chance it's the TCS temperature sender's wire.
The TCS sender is a water temp sensor screwed into the rear of the passenger's side cylinder head. It has one green wire, looping back another green wire to the connector. It's job is to tell the TCS relay when the engine temp is below or above certain levels. When those levels are dectected, the relay cuts vacuum off from the distributor via the idle solenoid mounted to the carb.
Good luck...

Link is good!!!
My money is still on the TCS temp sender. The sender is screwed into the passender head, and looks a lot like the main temp sender located on the forward driver's side cylinder head. It's hard to tell from the second pic, but does that wire go to a component in the cyl head?

A single green wire attaches to the back of the AC compressor for a superheat switch. Later compressors did not use the superheat switch and this wire is just laying loose. The end of this wire has a round conical shaped boot.
