3G Early Bronco Alternator Wiring Advice

For the best performance, we recommend pairing this early Bronco alternator with our #6025 Battery Charge Cable. If you are making your own charge cable, please use a minimum 6-gauge wire from the alternator to the battery.

After installing this alternator, the factory ALT gauge will no longer function. We suggest using our #6052 Voltage Gauge, which fits perfectly in your stock gauge cluster. Alternatively, any auto parts store volt gauge will also work to keep an eye on your charging system.

Mounting a 3G Alternator in your 66-77 Bronco

Mounting this alternator in your early Bronco is simple. The single wire connection makes wiring the alternator a breeze and it is simplified even more by using our #6025 Battery Charge Cable. Physically mounting the alternator to the early Bronco's engine is also simple. This alternator utilizes the factory alternator mounting brackets, so you literally just pull the old alternator off the engine and bolt this one right in its place.

"I've run one for ~10 years now, bought it from WildHorses. Very happy with it." - Mark S. on Facebook

My stock alternator was mounted low on the passenger side of the engine compartment. This alternator was too big to fit there so I relocated it high on the passenger side where it fit easily. I was able to use the factory bracket that allowed for both. The alternator works perfectly and wired up easily with the fused wiring that I also purchased from Wild Horses.

351W....Replacing an older alternator, but don't think it's the stock one. I definitely required the bottom bracket with the curve. I used the top bracket from a competitor due long lead times, but didn't fit. The two holes to the center of the block line up but were short on reaching the top of the alternator. I did require the smaller spacer for the top, which I believe is 1.675 (not confirmed) in length. Once installed, no problems running the 40AMP electric fan and lights.

Had a mishap with my old alternator, wiring harness melted to the engine block and caught fire...all was good though, just needed to replace Alternator and rewire. This NEW alternator was easy to cable up with 1 wire and I also purchased the HIGH AMP fuse and cable set as well. Only problem is that this 3G alternator is much different in size compared to my old one...a bit of modifications to my old Alternator bracket fixed the issue!

Bought this, along with the fuse kit (highly recommended) to upgrade my stock alternator at the same time I replaced my body harness. SO glad I decided to do it. Very simple upgrade and perfect fit.

This alternator was a great upgrade from my 1g alt Since it has a built in regulator, it cleaned up the wires in my compartment. So far, it has done a great job at keeping my battery charged.

This has been a great alternator. The install was incredibly easy (Hard to mess up one wire). At idle, my voltage stays constant unlike the 12si alternator that I replaced. Had a little problem with belt squeal (V-Belt) but after re-tightening, it has not come back. I did end up putting a longer bolt in the bottom tension hole to make sure I did not strip the case. I would definitely recommend this alternator.
