I recently did a 6G (2000 Taurus 3.0L) swap on my 5.0.
Had it in stock, so I used it after having a grey regulator installed (there are 6 different reg styles for this application :dodgy
.
The stock 5.0 2G's are fire prone (very poorly engineered OE charge wire and connector choices). One of my coworkers almost cooked his '85 LTD down to the ground this past weekend, so the "rumors" about them is true.
Anyhow, the 6G is very similar to the 3G, aside from the regulator. I basically reused the stock harness and added a 4 gauge charge wire with a 175A mega fuse near the battery. Would have been no problem to fab a complete "harness" if needed, but the gains would have been zero.
The 6G even has a provision on the back of the case for adding another ground to the frame for added insurance. I used a short piece of leftover 4GA for the secondary ground.
I will definitely install one on my '71 when the time comes. As for the pulley, I don't know what to do there. Haven't researched it enough yet since I'm still on the fence regarding the whole powerplant choice anyhow. I tried to install the aluminum 5.0 power pulley on the 6G but it is slightly different than the stock steel 6G (same diameter but different offset/spacing). V-belt will be a whole different game. Probably can find info via Google I'd bet.

Wiring is
super simple and straightforward. Works great on my Fox car.
