So I'm looking to swap in a 117A alternator into my 94 yj. So I need to do anything with the wiring?

If money is not an issue look at this.

I don't really need that many amps. I just need to keep up with my winch when I use it.

What Jeep do you have? If it's a YJ then you'll probably want to run another line from the alternator to the battery. The stock line is rated at 100a (two 50a fuses in the PDC). Although, that's at full draw and at high RPM. So yes, you could run it without upgrading in a pinch. You'll want to look at the load range of the wire gauge to figure out what you need. A 10 gauge wire would work but if you're going to do it you might want to consider something like a 8-4 gauge. Then fuse that or use a circuit breaker.

Would I run the new wire straight to the battery or would I replace the factory one and replace both fuses with bigger ones?

I'd run a new line to the battery. Like I said the PDC is limited to 50a. Unless you want to be upgrading the wiring inside the box, you're better off just running a new line. If you go with a 8-4 gauge, you wouldn't have room in the box anyway.

Ok cool. Thanks. That's my project for tomorrow.
