Do you want to upgrade your LS swap with the ability to burn that super cool corn fuel? LS Harness Connection plug and play kits can do just that! 
 
Included in the E85 sensor kit, you will receive an ethanol content sensor, 24" pre-terminated pigtail, 2x quick connect fuel fittings and a mounting bracket with front retaining clip.
 
Instructions are included with the kit, and installation is as simple as installing one pin into your engine controller, and providing power and ground sources. After install, you can add a sensor gauge in-line, get an updated tune, and hit the road with the peace of mind that you can safely run more aggressive tuning without risk of detonation, or take your pick at your local pump.
