Hello I'm troubleshooting the dash cluster instruments not working. The odometer is not working either. The rest of the dash cluster is working good. I performed the self test. It beep all the indicator lights work but the instruments dose not work.

I checked the two fuses, interior fuse box and the one in the engine compartment. Both fuse are good and 12v is present on both sides of the fuses. Checked and cleaned the grounding points.
I checked the wires behind both fuse boxes and they looked good.

Checked the dash cluster connectors pins and the wires going to the connectors. All looks good. I bent the pins on dash cluster and the instruments and odometer still not working.
I would like to check the dash cluster connector for 12v.
Does anyone one have a wiring diagram for these two dash cluster connectors and pin number orientation? Thanks
 
I found the problem with my dash cluster instruments not working.
It was the B+ (pink/white) wire that supplies 12v to the cluster. It was broken under the dash console. The copper wire was corroded inside the insolation. Just a small length of the wire was bad. Very strange.
 
You say it was corroded inside the insulation? How did you even find that?

You might strobe out all the other wires in that bundle while you're in there.
 
I've seen pin holes from people power probing wires that proved problematic. Time, water and condensation. And cheap Jeep wiring.
