It's common for high mileage 6.6l injector wiring harnesses to short out between the connector pins. Especially cylinder numbers 2 and 7. This often results in codes: P0202 P0207, P02146, P02149.
This pigtail allows you to easily replace the problematic injector connectors. Heat shrink crimp connectors are included to insure you have everything you need to get back on the road!
Fits: 2004.5-2005 6.6l LLY Duramax engines found in Chevy/GMC 2500/3500/4500 & 5500 applications.
