1990 xj 4.0 automatic 4x4.

I know about the one on the passenger side of the engine block. The one on the driver side on the back side of the valve cover. Where are more grounds located. Pics would be great but not a must.

 

Hope this helps.


From the factory wiring manual with a Ground Distribution page in it regarding lighting:

There are 2 points on the left inner fender.

There is the engine dipstick tube stud. SUPER IMPORTANT!!

There is the ground above the lower diagonal dash brace to the left of the steering column on the shiny part of the dash.

There is one in behind the trim panel where the spare tire mounts.

The one on the instrument panel grounds a ton of things. Probably too many things as a matter of fact, given it's poor mounting point on the panel with a self tapping screw. I remove the screw that it's held on with, add a wire, using 10 gauge, and terminate it to the stud near the fusebox.

There are also grounds from the engine to chassis, notably the poor one from the back of the head to the firewall but that wouldn't affect your dash lights. Not that the engine to chassis grounding shouldn't be addressed.

Thanks cruiser. Your always s big help.

 

 

The ground wire that you said is instrument panel. That panel is that? I have a 94 jeep Cherokee xj and the dash isn't working. Along with my wipers. But they all work when I'm on an upward angle.

 

The brown wire is likely burned at the switch and the switch is bad.

 

Thanks alot cruiser54. That helped alot
