Does anyone have the wiring pinout for the insterment cluster 1999 dodge ram 2500 diesel auto trans? I'm looking for help on the 4x4 light indicator that does not work however the 4x4 is ingaged and working, just no light. I checked the light its selt and it lights. just no signal at the switch at the CAD.

Thanks

What happens if you stick a paperclip in the plug for the cad?

I know Mike is working on the wiring, I don't know the status on it.  Have you checked the articles?

Yes I jumped the wires on the cad crossed them tyed them togather all of the above. I evan tryied a new ground directly to the battery and the light does not com on. I can pull the light from the cluster and test it and it lights so the problem is from the cluster to the CAD.  Its hard to trace the wire from the cluster in the dash to where it joins the lume below the radiator and goes to the CAD.  What route does it take? does it go to the passenger side or the driver side and does it join it with any other system in the process?

Thanks Curtis

Mike has worked through it

 

 

Does this all stay with the gray wire from the cluster C2?
