Well, I made it to Pull-A-Part yesterday and grabbed a couple of servo pigtails and a servo out of an Explorer. Here are the wiring diagrams...

As you can see Pin 1 on the servo and Pin13 on the cluster are NOT USED.
1995 Explorer Servo Wiring

All I should have to do is add the pins into my harnesses and connect the wires together. The ranger didn't receive this wire until 1997 apparently.
Also, as a side note, in 1996 and newer Rangers/Explorers, the cluster pin order was reversed. So, pin1 became pin16 and vice versa. IE, pin 13 became pin 4...
