The DSX Baro Breakout Harness breaks out the barometric pressure sensor, which allows the calibrator to restore proper calculations in the ECM for pressure ratio on boosted applications. This harness is entirely plug and play... No splicing of any factory wiring harnesses required.

A baro sensor (one bar) is not included by default.  Select above to include one with the harness. The cost of sensors from GM has gone up significantly, and so the pricing reflects this increase from GM.

DSX manufactured components are covered against defects in materials and workmanship for the life of the product.
