I have the stock 2G alternator setup in my truck right now. I have read about people having fire issues with them. My question is should I attempt the swap? The only accessories I have are a Kenwood HU and a 350Watt amp going to a sub. I do notice the charge is a little low and fluctuates a pinch when the amp is on. I have a 92 F150 with a 5.8. If I do the swap what vehicles can I get an alternator from? And what else do I need? I would like to go for a 130A if I can but 95A will be ok with me.
*Edit: Did some research online and checked the local Pick-n-Pull and there are 40 cars in the yard that have the 130A alternator I need. What else do I need? Wiring adapter? New power wire?

You'll need the charge wiring from the alternator to the fender solenoid.
If the car you pull from doesn't have a fuse & holder, you need to get one.
You'll only be using the green/red wire from your existing 2G regulator harness.
You'll need to clearance the aluminum casting to fit the 148mm housing of the 130A 3g alternator.
All the instructions are on Fuel Injection Technical Library
Hope this helps.
Ok well I think im gonna go ahead and do the swap. Ill source the alternator next weekend. Only $24 at the local Pick-n-Pull. I think I will go with the alternator charge cable from RJM that has the inline fuse already. What do i need to do for the plugs? Could someone who has done the swap possibly take a picture of the wiring that goes into the plugs on their 3G? Better yet, on a 5.8? Thanks
Just be sure to get the right (7" c-c) mounting.
I know the 3.0 V6 has these, because I use the larger 8.25" ear on my V-belt setup and needed to find one for a 3.8l Taurus.
If you know someone that has a 3/8-16 Helicoil kit, it makes it a lot easier to tension the alternator.
Because you only need one wrench to tighten and can then use your other hand to hold the tension.

Ok so I guess I have one more question. Im going to order this harness for the swap: RJM Injection Tech — 3G Alternator Harness
Now do I simply install the connector provided that isn't already attatched to the harness onto a wire and connect that to the starter relay? Im assuming that is what I would do.
