Check this connector behind the driver's headlight and in front of the air cleaner.

 

Thanks cruiser you are the man I will check that today. You are so much help

 

Ok hers some pics this is of the connector at the rear end that come from the fuse box. It's for I believe the wiper is tere any reason those two wires Gould have continuity between each other ? They are still connected up front as well with the wires for the rear defroster ?
Cruiser this is the connector you were referancing correct?
And can you tell me what these relays are for ?

 

2nd pic is the connector I was referring to.

3rd pic. Top is fuel pump ballast resistor, middle is EGR solenoid, bottom is relay for EGR soleniod IIRC.

 

Ok checked that connector corroded to hell cleaned it and tensioned it pulled the bezels and grille foud harness un sheathed it no issues. Went under the dash and jeez I Dont Know what I'm looking at here's something's I hope youcan help me with what is this thing
And what is this ? I'm pretty narrowed down to under the dash so far with this issue

 

Top photo is cruise control module. Bottom photo is intermittent wiper module.

 

Ok I have a big metal box on the passenger side of the Colum that says bendix. Is that the engine cu or an anti lock unit

 

So it's my understanding that If I'd disconnect the connector for the rear lamps at the left kick panel and leave everything back connected with good bulbs they should all have continuity between each other ? They all share the same ground ? Also I took the switch out and I have continuity terminal r and ground when switch is in postion 1 and then in postion 2 no continuity push it to postion zero lights off I have continuity until I twist the **** a bit? Normal or not?

 

Have you checked the wiring going to the hatch? The license plate light hot wire broke and hit a broken ground on mine (89) and cause my running lights fuse to blow. The box on the passenger side of the column is the ECM. My xj likes to blow brake light bulbs and have not found out why yet. And yes there's a main connector for rear lights looked between gas door and tail light behind the spare tire panel.

 

The hatch wires also plug in behind that panel. Depending on the options you have there's a plug for each option ex: rear wipe,defrost, power locks, and standard are license plate and speakers.

 

Yes hatch wires look ok the plate lamp has been moved from stock to the driver side due to a sore carrier

 

Ok everything from the main connector up front to te main connector behind the filler neck is good I went through that last night and soldered the groud splice cleaned the ground point below the window and respliced the blue runnig lamp wires so that is all good. Now where was your hatch harness broken I have a rear wiper defogger speakers power locks and spare tire carrier

 

Issue maybe resolved why the hell would they hook power straight to a ground comming from my plate lamps ?

 

ECU.

 

Pretty stupid. Shoulda left it alone, shouldn't they?
