Please contact us before ordering if you have any questions regarding the application of this pigtail harness. This is a 3 PRONG, AND "D"-SHAPED pigtail harness that plugs into the alternator regulator. Long term exposure to the elements tends to cause the plastic on the original pigtail to become brittle and crack/break. This replacement pigtail can resolve this issue. We pride ourselves on speed and accuracy!!! If you place your order before 3 pm Central Time, we will ship it out the same day (except on weekends). In a bigger hurry?? Please contact us before ordering if you need expedited shipping (Next Day Air, 2nd Day, etc.)

NOTE: THIS PIGTAIL FITS 2G, 3G AND 4G ALTERNATORS. LESTER PLUG CODES ARE 330,331, 333 AND 334. FOR THE 330 AND 333 PLUG CODES, THE TERMINALS ARE DESIGNATED AS "A" (BATTERY+), "S" (STATOR), AND "I" (IGNITION). THE 331 AND 334 PLUG CODES ARE DESIGNATED AS "A" (BATTERY+), "D" (DUMMY; NON-FUNCTIONAL), AND "I" (IGNITION). 

OUR PIGTAIL IS A UNIVERSAL DESIGN THAT CONTAINS 3-WIRES. BUT, DUE TO ITS UNIVERSAL DESIGN IT CAN REPLACE VERSIONS OF THIS PIGTAIL THAT ONLY ACTIVELY USE 2 OF THE 3 WIRES. SIMPLY ATTACH OUR PIGTAIL BY SPLICING  TOGETHER THE CORRESPONDING WIRES FROM YOUR ORIGINAL PIGTAIL ONTO OURS. THEN, TIE OFF OR CUT OFF THE REMAINING UNUSED WIRE ON OUR PIGTAIL TO COMPLETE THE REPAIR.

Typically, the replacement harness is spliced into the vehicle's existing harness by crimping it in place with a butt connector and crimping tool (not included). Please be sure to use sufficient pressure with the crimping tool to ensure tight crimps on the ends of both wires being joined. To verify that the new pigtail harness has been properly attached, use a fair amount of force to pull on both sides of the butt connector simultaneously. (USE ABOUT THE SAME AMOUNT OF FORCE AS YOU USE WHEN TYING YOUR SHOELACES).  The newly crimped ends should not give any slack at all. If the wire(s) begin to pull out away from the butt connector, cut the butt connector off and repeat the process with a new butt connector and make sure to impose sufficient force on the new butt connector with the crimping tool. 

THIS PIGTAIL HARNESS A 10 YEAR WARRANTY AGAINST ANY ISSUE YOU MAY HAVE WITH IT! EVEN IF YOU ACCIDENTALLY BREAK IT, WE WILL REPLACE IT AT NO COST TO YOU!! NO WARRANTY ON LABOR OR ASSOCIATED COSTS.
