You really don't need a fancy isolating switch. In fact, the simpler the better. An old fashioned big copper knife switch handles hundreds of amps and is really easy to visually check. And it pretty much never breaks.

That strikes me as very dangerous since it's pretty easy to drop a tool or somehow make electrical contact.

In my jeep I installed this HD circuit breaker for the winch so that power is off whenever not in use.

If you're using the Knife switch you may want to pick one of these Lucas Harness Smoke Replacement tools. Great for the originality crowd.

You know, the wiring on my Cobra is far and away of higher quality than on my daily drivers. This weekend I spent several hours chasing down, and finally finding, a faulty ground that is relatively notorious in the Jeep world. One headlight had gone out on me, and showed no ground feed at the light. When I ran a quick supplemental ground to the headlight, the dashboard brake light would stay on! When I ran a supplemental ground to the brake fluid sensor switch, I got the brake light to behave normally. Obviously my bandaid fixes were not the final solution and there was a sneaky ground issue somewhere. When I finally found the answer on a Jeep forum it was a faulty ground in a nine-wire ground bundle to the frame that fails invisibly up from the crimp. From the outside it looked absolutely fine and you couldn't wiggle it to produce any tell-tale effects. But when you cut it open, the connections would literally crumble in your hand.

Troubleshooting is fun and your wiring skills are good. I'm just giving you hard time is all.
