Anybody recognize this plug?

89 XJ, renix 4.0, aw4, 231.

Trying to clean up the engine bay as I swap in my crate engine D) and came upon this:



It comes off the harness just behind the battery, two green wires, about 6-8" long.

Obviously, it hasn't been used in a very long time, if ever. I'm just curious what it's for, before I clip it off. In case it's for something I might want to add.

Anybody?

Thanks,

Robert

That is the plug for the AC low pressure cut off switch that is attached to the AC condenser

That makes sense, the condensor's been gone for years.

Thanks!
