Was changing the bulbs of my instrument cluster today and came across this. Since I've had my ranger i have had no idea what it is or what it does, anyone know or have a clue?

It is connected to relay (shown above) if that helps.
Thanks

 

Welcome to the forum

What YEAR Ranger?

And 2WD or 4x4?

 

2000 ford ranger 4x4

 

Does the 4x4 electric shift work?

Not factory, of course

 

Yes the stock electric shifter works. I think I'm going to replace the relay and see if it turns on.

 

Miniaturized version of the Flux Capacitor. Instead of using a Mr Fusion for power, it now uses 12 volt via the relay..
Try going ahead 5 - 10 years and see what type of trucks Ford is turning out !!!
