As Tom said there were different gauges used. There are letters stamped on some of them that indicate what they are intended to be connected to. Be VERY careful and MAKE SURE you connect it properly. If connected incorrectly there will be a small poof of smoke and the gauge will be destroyed. The smoke is hard to pack back into the gauge...
It would help if you described the gauges. Two cluster or a single cluster. Early gauges had no ground wire connected an had two wires going to the sender and one for the 6 volt connection. Later gauges had only one wire going to the sender and only two terminals on the gauge. When 12 volt trucks came out they still used 6 volt gauges and had a reducing resistor dropped the voltage going to the gauge.
To properly advise you how to connect the gauge it would help to know the following:
1. What year and model Power-Wagon truck are you working on?
2. How many wires (1 or 2) connect to the sender?
3. What voltage battery are you using?
4. Has the truck been converted from 6 to 12 volts?
Note: The gauge and sender MUST match. A one wire sender will not work with two terminal sender, and a two terminal sender will not work with a three terminal sender.
You are welcome to ask me questions but it is difficult to answer without more information. Let me know if I can help, I be glad to assist you.
