I've got a 50 Chevy sedan, and didn't want to spring for the $130 internally regulated alternator, so I got the externally regulated one. I was just wondering, as I'm about to delve into the horrors of automotive wiring, where did you mount your regulator? I'm assuming the firewall, but I'd also be curious to find out where you ran the wires going to it. I'm thinking of buying a wiring book by this Tex fellah that's supposed to be the bees knees, but until then I would like to at least have the alternator hooked up so when I'm testing things out and tuning the engine I don't have to run it off the battery for short spurts and bust ass to get the job done in 30 seconds or less! Thanks!
