These harnesses are form-fitted engine harnesses for GM engines, utilizing all new wire and OEM components. The objective of these wiring harnesses is to have the wires well organized on the engine so that they disappear as much as possible and don’t detract from the look of the engine; all this while functioning to the complete OEM specs for engine control and performance. This is a self-contained engine and transmission control system that comes with its own fuse block and relays. In each of our harnesses all of the connections are labeled and placed in their proper location for ease of installation.

These stock kits include a complete wiring harness for the engine & transmission. Standard length of 4-FT from the back of passenger head to the ECU. All harness include installation instructions. Each kit includes a certificate for sending in the ECU for programming (included in the price).
