I have a free alternator from a late 90's chevrolet one wire. It seems to fit well. I would like to use it on my 1982 mustang. The old wiring on my mustang is confusing me. The old alternator wire connects to some fuse able links ( I think that's what they are called). I'm not sure how to rewire those with the new alternator. I see allot of how to with the 2g mustangs but not the earlier fox cars.

Unless you know the output current specs are better than stock Ford and have had the alternator tested to make sure that it meets them, I would pass this up.

Really, really, bad idea. If you want a budget alternator upgrade, find the 3g alternator upgrade tech article and get a junkyard 3g alternator.

Sell the free alt and go to the junk yard and get what you need.

3G install into an 85 or earlier Mustang:

I would recommend the addition of a 2 amp fuse on the Light Green/Red wire that goes to the switched ignition.
I would use a maximum of 125 amp fuse for the output wire that connects to the starter solenoid.
