Ok I am curious, on the extra wiring discussed on the detailed smithmonte site, what have people actually done on their upgrades?

4alterstart.com told me I wouldn't need an extra power wire unless I went to the 175 amp 3G, the usual 130 amp 3G is fine without.

I've go two fuel pumps and an electric fan. The stock wiring would have burnt up.

If you follow the two orange/black wires back they merge into a single 10ga (I think that's the size) wire which is inadequate for a 130amp alt. I know some have just attached the OEM wire to the 130 and it worked but some have actually burned up that wire.

Just put on a 4ga fused wire and be done with it.

I'm currently running around with a 3G 130A running a #4 wire without a fuse. I've got a fuse holder in the house, with fuses, but I haven't had time to make a weatherproof housing for them. Not really needed, but I'd like to do it right.
