New 94/97 LT1 (5.7 & 4.3 V8) stand alone SFI wiring harness. Our 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. 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. We have provided plenty of room for placement of the computer, each harness is exactly 3 feet from the rear of the engine to the pcm, with an overall length of 6 feet (from PCM to the furthest sensor connection). We have also supplied the correct rubber grommet to install the computer inside the car. Our harnesses remove all the provisions for the unwanted items that modern FI engines come with, for example no VATS system, no Charcoal canister, no air pump, no EGR, ect... which allows for a much cleaner installation. This harness is perfect for dropping any LT1 engine into any vehicle. This harness will work with the 96-97 LT1 but will require the use of an 94-95 PCM (service number 16188051) . PCM reprogramming is necessary for the correct transmission operation and antitheft removal, your PCM must have 16188051 as the service number found on the tag. PCM reprogramming is available from us. A list of connections on the harness is below.
