Could use some help identifying some loose wires

Hi folks,

Normally I am a CJ guy and can deal with wiring issues due to the lack of electrical accessories on my CJ keeping things simple but I picked up a 1989 wrangler recently and it has a couple wires I can't quite figure out where to reconnect.

I would appreciate it if somebody can identify these 3 for me so I can hook them back up.

Here is the first:


Here is the second:


And here is the third:



BTW- this is a 4.2L i6 with an automatic transmission (32RH)


Thanks in advance for your help!

Interesting. I went out and looked at my 89 and it has all three of those connectors and they aren't connected so anything.

The middle one I'd noticed before. I always assumed it maybe had something to do with the washer fluid. The other two I had never seen before and dug around and found them stuffed behind the wire harnesses.

BTW, your 89 looks one heck of a lot cleaner under the hood than my 89! My other (much newer) cars don't look that clean.

The first is the hot lead to the hood light, if equipped. A mercury switch mounted light under the hood near the passenger side hinge. Turns on when the hood is raised.

The second is the ground for the rear window washer fluid pump if equipped. There would be two separate pumps on the bottom of the washer fluid reservoir.

The third is obsolete. Originally the YJ had a computer controlled electrical valve which closed off the PCV circuit at idle, not allowing the PCV to vent gasses to the carb. That was eliminated by a factory recall later on. Thatís the original plug. You should have an unobstructed run from the PCV to the base of the carb.

Thanks so much for that info. I've got all three of those loose wires too, and wondered what they were. Now I know.

I wouldn't mind putting the hood light on.

Interesting. Makes sense since my Jeep has no hood light or rear window washer.

Thanks, just bought it 2 weeks ago and it is in really good shape. Paid $4500 for it.





But the motor of my CJ is cleaner
