Mods, can you please sticky this in the Tech section.....
Things you'll need: --6-8' 4 awg wire (car audio place is a good place to look and will have high quality wire) --2 10 awg ring connectors to fit on stud on back of alt. --2 ring connectors for the 4 awg wire (or just one depending on whether you connect it to the 12V side of the starter relay or directly to the battery) --1 small female spade connector for 12 awg wire (or stator plug--available from PA performance for $5) --wire cutters and strippers (<--for the wires, sthmarty panths!!<Officer Barbrady voice>) --Soldering gun
**Check the top hole of the 3G alt...if it is threaded, you can reuse the stock bolt. Mine was not so I got a 7/16 (or similar) bolt, nut, and a couple of washers. The size does not matter as long as it fits the hole. <--LOL, that's what she said...
PA Performance sells the wire kit (and alt's, of course) to make it easier and sometimes cheaper.
Disconnect the negative side of the battery. Remove the connectors going to the old alternator and remove the alternator. Depending on the alt. you get, you may need to grind part of the bracket down (Pic 1). Keep the bolts b/c you will be reusing them. Once the bracket is modified, you can install the 3G. Notice the 3G alt will have some different connections than your stock 2G, but you WILL reuse the D-shaped plug (Pic 2). Cut the wires on the rectangle-shaped connector as close as you can to allow more wire to work with (Pic 3).
Install the ring connectors on the 4 awg wire and solder them to ensure connectivity. Route the wire from the battery [or starter solenoid], behind the radiator, and around to the alt. (Pic 4). The connector on the other end depends on how/where you choose to connect it. I went with the ring terminal, but installed it on the positive battery terminal w/ an aftermarket battery terminal connector. I chose to go this route b/c I did not have much room on the 12V side of the starter solenoid.
Install and solder the 10 awg ring connectors on the 2 blk/org wires that were cut from the rectangular connector. Install the small spade or stator plug on the white or light yellow 12 awg wire (only remaining wire from rectangular connector). Refer to Pic 5. I used heat shrink first, and then electrical tape. Since the picture, I have replaced the spade connector w/ the stator plug from PA.
Connect both blk/org wires AND the 4 gauge wire to the stud on the back of the alternator (mine had a red plastic piece around it). Connect the spade/stator plug to the stator terminal on alternator and also install D-shaped plug. Refer to Pics 2 and 6.
Make sure all connections are tight and reconnect your battery. I run 13V’s all day long, even w/ A/C and my electric fan cranking.
If I missed any steps or info, please let me know so I can add it.
