Product Description

This kit is made specifically for the installation of a Ford 3G alternator on any vehicle where the stock alternator was EXTERNALLY regulated

We incorporate a new replacement external regulator box (as shown) to capture the proper circuit and retain the stock wiring harness along with our own 3-wire (3G Series) regulator plug. This kit allows the customer to retain the OEM warning lights and shunt type ammeter **

Installation only requires the customer replace the stock external regulator with the one provided, install the alternator and our 3-wire plug, then make one crimp connection from the original wires at the alternator. All alternator upgrades require a large (#6 or #4 gauge) wire be run from the output of the alternator to the vehicle harness.

** direct reading ammeter should not be used or should be bridged due to the significant increase in measured amperage with upgrade alternators

Installed this unit with the new 130 amp alternator and all I can say is WOW!. I should have done that years ago. Quick, easy install and my factory amp meter still works as intended without chopping wires up. No more dimming lights at idle and it keeps up with my electric fan even with power pulleys. One of the best upgrades my old fox has had in years!!!!!!!!

Yes, I would recommend this item to a friend!

The photos could be a little clearer and brighter but the directions were fairly straight forward to install the alternator upgrade.
