After a fire.....

It is an approachable problem In my 1964 Valiant, the dash harness was so hacked that I rebuilt it. I changed to a 1965 bulkhead connector since those have large buss-bar feed-thrus for the ALT & BATT wires (only year exc. 1963, had to cut opening 1/8" taller). I bought a 1965 Fury harness (~$30 ebay). I moved my good wires to that bulkhead, cleaning all female terminals, and repaired booger'ed wires. I totally rewired the engine bay in all 3 of my 1960's Mopars, using a Jeep fuse/relay box. I got rid of the factory horn & starter relays for the Bosch type in the box, plus relay'ed the headlamps, ignition, fuel pump (added EFI) and such. I ran smaller ribbon-cable for most circuits from the bulkhead to relay box. I also added a shunt diode to bypass high currents around the dash ammeter, plus added fuses to all circuits.
