I have a 1990 Jeep Cherokee with 4.0. I'm trying to fix my big issue with it and while I was inspecting things I came across this wire that looks like it was pulled out somewhere. I have no idea what it goes to. It is in the harness that goes to the O2 sensor and the knock sensor. Its bare, has no insulation on it. I figure its a ground but can't find anywhere it goes. Its wrapped with a heat sheild type tape with the two wires that go to the knock sensor. Anyone have any ideas. Thanks in advance.

 

Believe you should have ctsdown there.

 

It goes to the svfister valve...and on to the 30 weight ball bearings.........

naw, jes kiddin...... any way to post a photo of this rouge wire?

have you used a meter on it to see if indeed it does go to ground?

have you a wiring diagram for your year?

just my thoughts sir.....

post a pic, am sure someone will say "oh yeah....THAT f**n wire!!!"

cheers!

Got a pic ????

 

Hopefully my pics will load. Sorry about the bad pics. I know that its a ground. But I would like to know where it goes. I called all my buddies that I know with Cherokees but they all have 94 or newer and I guess they don't have knock sensors.

 

Checked out another Cherokee and the bare wire goes to the knock sensor plug. Guess it got pulled out of it some how. So next JY run grabbing a plug.
