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. This harness is perfect for dropping any LS1 engine into any vehicle. PCM reprogramming is necessary for the correct transmission operation and antitheft removal. We offer PCM reprogramming.
