Hmmm... I've never done the job you are trying to do... based just on the picture you took it looks like it might be held in place by a C-Clip... if this is the case you need a pair of "circlip" pliers (auto supply store). Like I said though I'm just guessing based on the picture you took...

I was hoping that it would just unplug, but that is not the case.

Wait... someone will be along who knows for sure...

You need that connection. That is the speed sensor that senses the compressor speed & sends it to the Kilma relay.

Thankyou, but how do I disconnect it?

I always find it useful to look up the parts and see what's involved. Looks like a simple spring clip and an O-ring.

That is what I needed, thankyou.

Well I'll be dammed... my instincts/guess was right. LOL.

Yes, thankyou for your help. Got it done, what a pain in the a$$!
