After years of playing whack-a-mole with electrical gremlins in my 1971 Volvo 1800E, I decided to start from scratch with a brand-new wiring harness. However, as you can tell from the nearly two-year absence of updates on this project, you can see that it’s no mere weekend project. Still, it’s not impossible, especially with the right tools and plenty of planning.

THE WIRING KIT
A universal wiring kit is just that, universal. The 12 circuit Painless fuseblock and harness (PN 764-10102) I decided to use is meant to be adaptable to most generic automotive electrical systems.

For instance: The horn circuit has its own fuse, horn relay, horn switch wire and horn activation wire. The headlight circuit assumes you will be using a standard foot dimmer switch and has wires for brights and low beams. Everything is very straightforward and clearly intended for wiring an American hotrod using some combination of domestic switch gear, alternator, turn signal indicators, etc.
