New 2007-2014 LS3/LS7/L99/Vortec stand alone SFI wiring harness. 58X system for use with E38 ECM. Harnesses are all made with top of the line copper strand wire. Each harness comes complete with the necessary relays and its own fused power source.

Harness does not include the connections for the alternator, emissions related items, displacement on demand (DOD), or the air condition. Each harness comes complete with full technical support by phone or online. Our harnesses come completely loomed with automotive grade split loom. We use all GM grade connectors. Installation consists of simply laying out the harness on the motor and plugging in the various devices. Comes complete with detailed instructions. We have provided plenty of room for placement of the computer, each harness has 3 feet from the rear of the engine to the PCM, with an overall length of 6 feet. Our harnesses remove all the provisions for the unwanted items that modern fuel injected engines come with for example no VATS system, no Charcoal canister, no air pump, no EGR, no rear O2 sensors, ect... which allows for a much cleaner installation.

ECM/TCM reprogramming is necessary for the correct transmission operation and antitheft removal. We offer reprogramming services.
