Wiring And Gauge Installation Made Easy

I haven't met too many folks who have enthusiastically dug into their rig's electrical wiring without some confusion. At first glance, a vehicle's electrical system and the installation of new gauges seem as if they would require a degree in engineering or at least weeks of studying wiring diagrams and schematics-but that isn't so.

The idea behind this scratch-built Scrambler is to construct a vehicle that I know like the back of my hand and that will hopefully last a lifetime. Sure, I may work my way through a few engines and transmissions, but when any component need replacing I'll know exactly what it takes to get the job done. All vehicles should be built this way.

I've rewired entire vehicles from scratch and installed gauges before, so I can tell you it can be a major pain. Chasing electrical problems is time-consuming and irritating, so I picked up a Painless Performance wiring harness for an '81-'86 Jeep CJ. I also rounded up some cool new Pro Comp Ultra-Lite gauges from Auto Meter. The Painless harness is bundled and complete, and the Auto Meter gauges are a breeze to install. It would take a book to show you every electrical hookup involved in this installation, so here are some highlights.
