3g alternator upgrade
(Click here to view the original thread with full colors/images)

I just got a 3g 130 Amp alternator to put into my 89 5.0 and I was looking at pa performances how to on it and they say you should get a new 4 gauge power wire. On their site they say that it is required for 130A upgrades but I haven't seen people using it in other how tos. Can anyone give advice on whether or not I should get this. They want $60 for it here http://www.pa-performance.com/displa...@1,nextN um@2 and I just dropped $150 on the alternator so I'd rather not have to buy it if I don't have to.

Yes you NEED it. The stock 10G wiring cannot handle 150 amps.

I bought 4ga battery cable from AZ for $10 or so and ran it like that with a couple crimps. My 3G conversion is a junkyard '95 alt, so unsure what comes on the PA alt, but all you do is run the 4GA wire from the power post on the alt to the pos side of the solenoid.

Also, you will notice to black/orange stripe #10 wires that went to the old alt. They are in a 3-wire harness with a small white wire that should now be connected to the new alt. Disconnect and tape up the two #10 wires from the alt only, do not disconnect them from the starter solenoid as the votage regulator gets power from that end.

HI,

I did the Pa upgrade to oue show car and yes you need the 4G wire. It's a breeze to install. We sell them in our store. Did you get the small case 130 amp?

I did, it fit perfect didn't need to drill anything
