Stop in for a cup of coffee

Many years ago a friend had a 68 charger, another guy offered to wire in a stereo, smoked the wiring from fusebox to headlight switch. Was a mess.
Had a similar one with a kenworth,dash harness burned. 70 some-odd wires to replace.
It was a metal clip in the dash that rubbed through. Wiring harness sat on it,in its proper retainers. That one was a mess.
