This item is garage sale priced because it's the older version with 14 circuits.




One thing to never forget - the wiring in your muscle car is forty years old and updating to modern and safe components is easy. This Painless Wiring harness features many pre-wired connections and is color coded to make installation a snap. This customizable 14 circuit harness can be used in almost any application where you want Mopar color coded wires. This harness elimintes the troublesome bulkhead connector and uses our unique covered micro-fuse block. Also featured is an auxiliary circuit with a 20 amp relay for accessories such as fog lights, or an electric fuel pump. Each wire is custom printed with the circuit identification for easy installation. 

Designed for 1966-76 Chrysler/Mopar muscle cars including Baracuda, Imperial, Belvedere, Satellite, Charger, GTX, Dart, Road Runner, Challenger, Demon and Duster.
