Where do I ground the AC clutch?
I recently replaced my AC clutch coil after reading that can be an easy/cheaper repair than a new compressor. With that being said I installed the new one I bought but don't know where to attach what looks to be a ground. Any suggestions? The picture shows the old one with it looking like the previous owner just put it on the coil itself. This wire is much longer on the new one. I checked the pressure on the low side and it was reading very high but that could be because the system wasn't engaging the compressor at the time. Any help is appreciated.
The wire I'm most concerned about is like the one on the right but just maybe six inches long on my new one.

Some questions. First, did you bump/jump the compressor to see if the old coil pulled the pulley tight when it had power? Next, have you watched the Modmini video below? The clutch does not have a ground (mine did not) as it held tight to the compressor via the o-ring. Last, the second link is to a thread with a good video on how auto AC systems work.

By "jumping" you take a wire/lead/clip and touch the positive side of the connection with a positive side lead while either having the compressor "grounded" to the engine or by connecting/touching the compressor with a negative lead. Similar to jumping a battery with jumper cables (that you could use for the this purpose).
Take a picture of your clutch and of the compressor and post them here.

At 6:26 in the ModMini vid he holds the compressor so that the pulley is up and he disconnects the power lead. His thumb is pointing toward the right side of the screen. Picture a clock with his thumb pointing at 9, there is a silver colored screw to the right and up, 12 on the clock, that holds the shroud I talked about above in place. You should be able to attach your ground wire to that screw ( I would use a round crimp on wire connector).

Wire that looks like it should be grounded but way too short to reach up top in the engine.
