I have a 143 Amp alternator on the shelf of my garage, and have been wanting to do this swap....



The back of the stock alternator has plugs on it, not terminals...



Do I just rerun new wires?

it's automatic.

Yes. Preferably heavier gauge ones...so they don't melt.

I have detailed photos of the new wires I ran, see the links in the first couple of posts. Use 4 gauge (or two 8 gauge in parallel) as a minimum for 143-150A.
