Need to know which wire is which for the power, ground, and level for the fuel level sender. I replaced my ghetto rigged 3 female disconnects with an actual 3 wire plug i kiped from the old radio connections. It seems the wires have gotten mixed up in the process and my guage is reading nothing. Thanks ~Gavin

 

How bout the online wiring diagrams? They ought to help you out. Also, you gotta state your year as these things do change from year to year.

 

I drew one up in paint a while back when I was doing mine, so I've searched up the old therad for you :

Unfortunately that doesn't tell you which one does what! But if you have a Heynes, or know someone who does, you can find the info in Chapter 13 if you have 3 wires. Mine is with my car at the moment, so I can't really look it up for ya.

Black is ground.. Yellow goes to the guage and if you have a third wire (blue/yellow stripe, I think), it goes to the idiot light. If your guage isn't working, you are in good company.. I've checked everything with no luck.. One wiring diagram I have shows a voltage regulator somewhere in the instrument panel. Gotta find it next.. Good Luck
