66 valiant wiring help

Your melted firewall connector is a common problem in 66+ A bodies, and continual warnings to fix that on FABO.

I replaced the "in fuel gage" dash regulator with an electronic one. Search "voltage limiter" and "Plymouth" on ebay, or the link RedFish gives.

If you feel really ambitious, look at my engine bay re-wiring, search "Modernized Engine Wiring" on FABO.
