An "Internally Regulated" alternator actually runs from 3 wires. These are the "common" units that are installed from the factory. They are what they used to replace/update the older externally regulated units.

No you are definitely right and I am not meaning that they are one and the same................it is just that all of the current trend is to "think" that the one wire and the internal regulated alternators are the cat's meow. They are sold by Summit and Jegs so everyone thinks they are the hot set up for their street machines...................not so!

I had a chrome 1 wire alt built for me at a local Auto Electric shop. Cost $130 and looks/functions great

Not to get too far off topic.
Personally, I'd ditch that glass fuel filter before you burn your truck to the ground & ruin your whole day.

They look nice & all, but all you have to do is have it break and pump gasoline all over your hot engine, especially if you're driving.

Just my .02.

If you go to Madelectrical.com and read the articles you will understand why I am trying to point out that the one wire set up is not the way to go unless it is on a tractor that doesn't have lights or accessorys or a drag car.
with the 1 wire set up the aternator only puts out a set voltage and will not "scence" that there is a voltage drop downstream at the headlights for instace, and it will not "know" to step up the voltage.
Don't take my word for it and this is not based on my general "opinion" either, just read the articles and you will undestand what i am saying.
