Hey guys i was wondering if someone could explain to me the process in detail of how to upgrade the 75 amp alternator to the 130 amp(like what wires to splice,ect...)I will more than likeley be getting one of ebay that comes with the neccessary harness.I have heard that it is not difficuly and should take about an hour tops.But i just dont want to screw it up.

it is easy...one connector will click right into the 130 AMP...the other connector has 3 wires on them. cut them all. Two of them I believe are black and orange...they are the larger gauge cable....crimp them together on the same eyelet connector....this will be fastened to the post on the back of the alt... The smaller wire needs a single pole connector and it plugs right on the 130 AMP...no extra special connectors needed....if you need help...let me know...it takes 10 minutes to do....

i would much rather see you use a new cable from the post on the alternator to the solenoid on the fire wall. something around 4 gauge

Unless you're using an aftermarket alternator bracket you'll need to notch your bracket due to the 3G having a larger housing.

i notched out my bracket with a dremel tool and took me about 20 minutes taking some off and rechecking the fitment. but like they said its real easy. good luck.

ok so im confused?The key is to use the same harness that the 75 amp was running of of right?I just have to modify it a little .What do i use the harness that comes with the 130 amp for?Do i just need it for the plug on it?Also would it be afer to use the 4 gauge wire running from the alternator to the firewall?

ODB

when you get the alt...call me....I will do the wiring for free.....I will show you how to notch the bracket....no joke 10 minutes for wiring.....don't sweat it.Forget everything else..........don't worry about the 4 awg......don't need any other harness'...you will use only what you have already.........just get the alt.......
