Best e85 sensor for the trucks

Very easy to install, took longer to jack up the truck than to actually install the sensor, can’t wait to see what it makes on the dyno

Harness was pinned incorrectly.

After boasting to my tuner how this product was plug and play it was brought to my attention that the sensor was not reading ethanol content. We tried switching the sensor with no luck. Tested power to the unit, Unit had power. Tested continuity ecm. Tested out fine. So we pulled back some of the sheathing and found the extension bracket was pinned incorrectly. 1 star for loss of time and diagnostic
