This is a GM Flex Fuel sensor with a custom made harness. This is ideal for people who don't need the plumbing side of things because they're using an aftermarket fuel system or just want to do things their own way. 

When checking out, select which ECM you have from the drop down below (most will fall in the E38/E67/E92 category). In the notes for your order, please specify the length of wire you need from the nearest ignition coil to the sensor (wherever you'll put it), and length of wire from the ignition coil to the ECM. IF YOU DO NOT LIST ACTUAL DIMENSIONS AND INSTEAD JUST LIST THE APPLICATION, WE WILL CANCEL YOUR ORDER!

DSX manufactured components are covered against defects in materials and workmanship for the life of the product. GM sensors are warrantied for 90 days.
