RWensing post and Although I had my auto dim mirror already hook up it was then when i saw the part in bold did i decide to redo the particular wires.
Tap the black/light blue of the overhead console into the black/light blue that goes to the factory Ranger dome connector.
Tap the light green/orange wires of the sunvisors and overhead console into the light green/orange that goes to the factory Ranger dome connector.
The dimmer wire of the overhead console is either red/black or light blue/red depending on the year. Tap it into the light blue/red of the ranger's radio harness.
The overhead console power wire is gray/yellow. Many how-to's tell you tap it into the yellow/black of the radio harness. That's OK unless you are also going to install the autolamp mirror. In that case, it is better to tap the gray/yellow of the console and the red/yellow of the mirror into the Ranger's gray/yellow - it can be found at several places but the easiest is probably at the heat/AC control panel.
This change will keep the autolamps from turning on the headlights needlessly after dark when the ignition key in the ACCESSORY position.
Blue/white and blue/yellow to the same on the ambient temp sensor.
Gray/black tapped to the gray/black of the GEM.
Black to chassis ground.
