I've got a 1975 dodge power wagon. My after market ammeter shorted out and screwed things up, besides that all my wiring is old and brittle and broken. Where can I go and get a good wiring harness? I rolled the p/u years ago and when I put it back together I used a 1977 cab. The harness from the steering column didn't quite match the harness going through the fire wall, but it worked with the exception of having to install a remote starter button. If I didn't like this OLD truck I'd light a match to it and forget it, but they don't make em' like this anymore. If I can't climb a hill like these newer trucks I've got four flat tires including my spare, and I can't get it into 4-high HA!
