Thanks, does the 3G require a voltage regulator?

No regulator is built in.

I have a 3g on my cobra works as it should, I ran the Voltage sense wire (BLUE) to the accessory side of the fuse box. The 3G is available easily at any parts store not to expensive and works great. I have one on my 65 tbird for 14 years 130 amp version no problems what so ever.

BTW if you need the plug for the 3g Standard Motor Products makes the plug for $18.00

Thanks Joey. What year and model of car/truck would you ask for at the part store? Mustang or truck? You know how these kids are at the part stores. Very few of them are car people and they have never wrenched on a car before. They only have a computer to look stuff up.

I just ask for a alternator for a 1999 Ford Taurus 3.0L V6 130amp version.

My 130 amp 3G is from a 1996 Mustang V6. It's actually a junkyard pull, and I grabbed as much of the harness as I could, including the 175 amp mega fuse - though I did need to purchase a holder for it from a local battery & alternator store.

Here are 1G to 3G conversion instructions: https://www.motortrend.com/how-to/in...r-older-fords/

Wiring diagram:

Here's part of what makes 3G alternators so good - higher output that starts at much lower RPM. Also note a 130 amp alternator can go much higher than it's rated output - which is why the matching mega fuse is 175 amps.
