Did a search but...

Brain-dead simple mod, I bought a 1-wire powermaster and did a write-up. Well sorta, my page has too much on it to be a good reference for the 1-wire upgrade.

Basically you just connect the single wire to a lead on the starter solenoid where the juice can get to the B+. Cut/insulate/hide the rats nest of wires from the old alternator/regulator and you are done.

I have an MSD distributor and 6AL ingition, as well as a latemodel starter (no more solenoid on the fenderwell) which meant I did not have to figure out what to do with the other wires so for that part I cannot help you. My suggestion is that you go to a late model starter at the same time as the late model alternator.

I bought a single wire 100 amp Powermaster Alt. from summit racing about two years ago for my 68 - 302, and have been pretty pleased with it. only having one wire sure helps "clean" up the engine compartment........

i also, have a powermaster like the above posts, one wire simple hookup

this might help

it's actually from the powermaster website and can help you pick an alternator...or at least the correct amp rating. also check out the FAQ, it has some info on "how to hook up a 1 wire alternator."
