130amp alternator on 2.8 ranger

[Takoda]

Was wondering if anyone had done this with success. Also if I can get an alternator if it was possible to just wire it up with out a mustang harness. I cant seem to find a doner mustang anywhere.

You can make your own harness. It's mostly a matter of having the right size wire to handle the current and putting the right connectors on the wires.

Should I go by the diagram thats posted in the tech page for this upgrade?

I'll have to check the article later. Or maybe someone else will answer. I'm setting up camp right now.

I have a alternator shop near me and he made a 200 amp alternator out of my 90 amp. All I had to do was beef up the wiring.

I'm running a 130amp mustang 3G Alternator on my 2.9L, with zero issues.
Lots of installation information here on TRS, and online.

I think even ETCG has a video on this upgrade.
