Jd 4320 wire ID

[Mallard1]

I plan to add a solenoid operated valve on the rear of my 4320 compact and found this wire connector that is capped and would like to use it. Can someone tell me what it is for. It is on fuse 05 that is the 妬gnition run power fuse. Yellow and red wires just behind the è�Ÿassenger side of the rock shaft arms. Yellow wire is labeled 594A. Is there a pigtail available that will plug in to keep from cutting the harness? It’s the two wires in the center of the picture that the plug cover has a small loop on the end

Just figured out it must be something for the mid mount mower because without the cover, which is actually a jumper, both the 540 and 2000 pto lights come on when pulling the pto knob. Also with it unplugged you cannot operate the pto knob off the tractor.

I did find another pig tail that uses red and looks like purple. No cover on it and runs on the same F05 fuse. Any idea if this would work?
