Just as expected

I’ve been having a hard time finding this wire harness to replace a chewed up 20 year old set. These came in super quick and fit perfectly, install was a breeze.

Coil Harness

Posted by Kyle V on Oct 20th 2022

Bought this harness for my 2000 Silverado after my OEM harness was chewed up by rodents. Fixed the issue and we’re back up and running. Highly recommend. Plug and play.

Works well in a 5.3 vortec engine on a chevy 2001 Silverado. Truck works great!

Ignition coil harness stick location

Posted by Phillip cox on Feb 17th 2022

Wiring harness fits great I would suggest this to anyone who needs them. I used the factory harness and had a problem with misfires that I traced back to the wiring harness so I saw these and figured I would give them a try. Great price too.
