These Mopar dash lights are a bit of a "trick."
The circuit path is as follows:
(First of all the headlight switch has TWO separate power sources, one UNFUSED power from the ammeter circuit ONLY for the headlights. The second comes from the TAIL / PARK circuit fuse
That last power goes through the switch (in park or headlight position) out the DASH DIMMER CONTROL on a tan wire and down TO the INST fuse in the fuse panel. Then the dash lighting is distributed on ORANGE wiring. So start by checking in the fuse panel, while making sure the tail/ park lights work
Bear in mind the INST fuse is ONLY HOT with the light switch in "park" or headlights and the tail circuit working, AND with the dash dimmer control rotated "to the left."
Also stop over to MyMopar.com and download yourself a free service manual, as well as an aftermarket diagram. Bear in mind those diagrams are not always as detailed or complete as the factory ones in the manual
