Great product that works as intended. Plenty of wire to run it wherever you have a +12V switched power source. I have a105amp alternator on an LS3 swapped ‘78 Firebird. Alternator charges perfect with this pigtail.

Does the job. High quality connector. 96" seems like a lot however it was just what I needed without adding splice.

I used this adapter plug in a 4 wire alternator where I set it up for a single wire use and it works perfect.This pig tail assembly already has the resistor built in so you don't need anything else but to wire it into a 12v source.

My Holley Terminator X Max doesn't have alternator control so i picked this up. Plugged it in and ran switched 12v to the wire and my alternator started charging,
