Ascribing "value" on something like this is tough. I'm having a friend do my harness, but if I wasn't I'd be looking for super-reliable options as well. Having been driven mad before with all manner of electrical gremlins on old cars, I can see the value of dropping some coin on a well-developed solution.

BTW, Brando do you always work on your car barefoot? Oh wait [as he checks location], yep, knew it...California.

Best,
