Swapping in an 8.1L (8100, L18) Vortec or an 8.8l PSI into a setup with an LS (4.8, 5.3, 6.0, 6.2, 7.0) harness? We got what you need!! This harness connects to a 24x or 58x Crank Sensor Connector, and extends 32 inches to reach the 24x Crank Sensor found in the top, back of 8.1L block, or the 58x sensor found in the 8.8L. Wires are already changed to fit the 8.1L Sensor. No modifications needed.
Harness is comprised of OE terminals and seals, 1 OE connector, and 1 aftermarket connector, which allows for both the Black and Gray Cranks sensor connector to mate to the harness. 18awg TXL is used, spiral bound, and loomed in High Temp Tesa 51036
Your PCM MUST be capable of running the cranks sensor you have. P01 and P59 are limited to 24x. E38 and E67 are limited to 58x. Holley Terminator X, and other Holley systems can run either. The crank sensors will work of 12v or 5v, with no issues.
