Re: is a?
You are much better off with a traditional 3 wire internally regulated alternator. There is a very good explanation Here
BTW, it is a very good idea to make your post title an actual question, related to your actul question is best.

Re: is a?
I swapped in a '87 Silverado 94 amp....didn't have to buy a kit either. Works like a charm. You can find the article in the FAQ section.
All you have to buy is the alternator and wire a couple of leads together at the regulator plug. With 94 amps you can run everything you need to without worrying about the amps drawing down too low. I know nothing about the kit, but I do know that my one wire beats the pants of any stock alternator setup regardless of the number of wires. 94amps is simply much better than 62! PS....the alternator I used is available anywhere. I bought mine at O'Reilly's

While there may be some merit to the idiot light not working on the one wire and the "remote voltage sensing" of the 3 wire, most of the other info in that article is bogus. Right here is the first clue; Quote:
I can't remember exactly how to wire a 3 wire right at the moment, but I know it can be done for a couple bucks. IIRC, all ya need is a few feet of wire and a couple spade connectors. I'm guessing this would be their "kit" they're selling for 28 bucks. Any 10SI, (and probably the 12SI too, but I can't say for sure), can be converted to a one wire alt in a few minutes by just swapping out the normal internal voltage regulator for a "self exciting" regulater. That's all there is to it. Everything else is the same. I just did this conversion, (again), 2 days ago for the alt on my motorhome. If anybody needs/wants pics of how to do it, I haven't put the alt back on yet. I'd be more than happy to split it apart again and snap some pics. The normal regulator is still layin on my welder as a matter of fact! LOL If ya have a friendly alternator rebuild shop locally, just go in and ask 'em for a self exciting regulator. The last one I bought cost about 12-14 bucks I think. I carry an extra one in the glove box just in case it fails. But I've been using the "one wires" on various vehicles for close to 15 years and never had one fail yet. To be sure ya get a self exciting regulator, the part number on it will have a SE in it.

And to look at the regulators themselves, (3 wire internal vs the 1 wire internal), they look identical. The only difference is the SE on the part number. The 1 wire even has the 2 spade connector terminals, (that don't get used). I've never figured out why they went ahead and put those terminals on the SE regulators.... Doesn't make much sense to me. LOL

Re: is a?
I have a 100 amp one-wire alternator and love it. Had it for 4 years now, and no problems, plus less wires = cleaner engine compartment. I see them on all the high dollar hot rods, so that is good enough reason for me to have one. With the extra amps, you will have no problems with running other accessories as well.

Re: is a?
I also recommend a local alternator shop whichever route you choose...I have always had problems in the past buying from chain parts stores when it comes to alternators. My local guy is the one who recommended a one-wire alt, and also wound it so I have 100 amps output.

You'll be eliminating basically all the wires that go to the original alt. and regulator. Ya just run one wire from the post on the alt to the pos (+) post of the battery.
