The crate motor on my 81 is a GM turnkey with a newer style AC compressor. I found what I expect is the correct wiring harness adapter to go from the old style clip to the newer style. I had 2 questions.
1) Does anyone have any experience with this situation and does this look like the correct solution? I don't want to cut the harness. I'd much prefer to use an adapter to bridge the difference. It looks like the connection would be two male ends making contact. I didn't find this harness with a female end, so I have to assume the contacts are sufficient, but am curious anyone else's experience.
2) The capacitor/fusible link(?) on the old harness (see the red arrow)....would I leave that in place? I don't know its purpose and if it's compatible with the newer compressor
That is not right to have two male ends touch to make a connection. I would splice (solder and heat shrink the new connector on to existing harness. Too much current to hope the males being close together to work. You can add a capacitor after the fact if you have a original radio but aftermarket radios do not need the suppression
As long as the terminals are clean, the adapter is-ok.
The oe harness connector has female terminals (should be the kind that can connect to spade or T type terminals) the adapter plugs into, then the new style plug fits the new compressor clutch coil.
Piece o' cake.
But, then again, I could be wrong. Good luck.

Reason: Clarification
All an ac clutch is , is a electromagnetic coil. You got a ground and a 12V supply when you turn it on in the cabin. Two wires. Irregardless of how those two are connected electricity flows through the coil making it a magnet.
So yes your connector will work fine. Or you could snip the old connector off and solder on a new one, doesn’t really matter.
a capacitor runs ac ripple, or dc ( pulsing dc) ripple to ground so that it is not introduced into the electrical system which can be heard in your radio as a hum or clicking/ static.
