Sending unit wires?
I am trying to get my temp and oil gauges to work and am trying to find just the harness that goes from the dash cluster to the sending units? If i sound crazy sorry, trying to explain it the best I can

Looks like they use the same wire colors as the later trucks, red/white and white/red. If you want to test the wiring and the gauges, turn the key to run and get someone to watch the gauges as you take the sending unit wires and ground them and then unground them. Each time you do this the gauge should swing full scale down or up.

Find another piece of wire and joint it to the piece you have. You probably will not be able to find a piece of wire that will match color wise, but that won't matter. If it does, you will have to go to the junkyard and cut a piece off a junk truck.
The best way to join the wires is to slip a piece of shrink tube over the wire, solder the two wires together, then slide the shrink tube over the solder joint and shrink it. It looks very professional this way. The other way that will work is to solder it and then use electrical tape to insulate it. Not as neat looking but works well.
Another way is to use a crimp butt splice and then tape the butt connector. This is not as good a soldering, but if this type of connection is out of the weather, it will usually hold up, and is quicker and easier if you do not have a soldering iron. I would not use any type of crimp method underneath the truck, ie like the back bumper area for a trailer connector.
