If you build one of those boxes, make darn sure you feed it with an ample sized feed line. I see these things all the time being fed by a single 10-12ga wire.
Serious?!?! That's crazy. If I were to build one, I'd probably use 2 gauge wire with 4 gauge being the minimum I'd use.
For now, I'm using your headlight kit and it works great and easy to install. I'm even using your alternator wrap around to feed the Toyota alternator which works great as well.
