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.
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).
Connnector pigtails are sold with OE quality terminals and seals. The wire is high quality which is made of tinned copper strands. This allows for better corrosion resistance, excellent conductivity & makes repairing/soldering much easier.
