Default New Alternator Install

ok so i was gonna go all out and get a 100 amp chrome 1 wire alternator but i figured id get something to hold me over right now for $40 bucks and not work against myself saving for the paint job....

so i got the stock 61amp replacement...i know i prob wont be able to run any modern things like CD player, fog lights, any other sort of lights or whatever...but oh well...for now i guess....

im about to switch my alternator out, so if any of you guys have some tips or some kind of guide...etc....let me know....thanks!

Whenever you replace the alt always put in a new volage regulator.

Mark where each wire goes by using masking tape to write on, then attach that tape to the wire so you will remember which wire goes where. But, if you screw up and forget, we have a wiring chart for the alternator in the FAQ. Just make sure you keep the same colored wires if you replace them, or mark on the tape what color the old wire used to be.

I doubt it. Mustang supply places have them but they are pricey. Texas Mustang has them for $102.95. If I were you, I would manufacture my own harness. There are not that many wires, and it is a relatively simple design. If you do decide to build your own, then get several feet of wiring loom when you buy the wire. That will organize the wires and you can tuck that in nicely on the bottom of your rad support with the wires that go to the regulator. You will need two or three different sizes of wire. Just look at your old wire and try to match the sizes. You probably can't get the striped wires, but make sure you have three or so different colors, and only change one wire at a time so you don't get confused about which wire goes where.

You can get the harness from Virginia Mustang for $22 or $30 depending on your engine size and whether you have a tach or not. Just go to www.vamustang.com and type alternator harness in the search box and it will list all the models.
