[QUOTE=ls1nova71;8152170]1 - I don't have a part number, but it was just a 12v LED that I picked up at Radio Shack.
2 - you can use what ever you want, but I like these.

3 - To follow the printed circuit board, you just have to look at it. The gauges are bolted to the printed circuit, the 12v powers will all be hooked together, so by following it, you should see it. The grounds are usually grounded to the tin, and the sender wires are separate. Just follow the printed 'wire' from the gauge back to the original dash plug so you know what each wire does. I really cant explain it any more than that, but if you cant figure it out, you may need to find someone in your area that can either wire it for you, or at least help you out with it.
4 - You don't have to put a volt gauge in, but there really isn't any good way to get the original ammeter to work with the LS alternator, so that's why I change them. If you can live without that gauge then you don't need to do anything.[/QUOTE
Ok Thanks for the info I'm gonna try to work on it tomorrow I'll let you know if I have any issues
