Tuned Port Injection stand alone EFI wiring harness . This harness takes care of the headaches involved with installing Tuned port injection on most all SBC engines or swapping a TPI engine into your vehicle, and makes for a much easier installation. 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 detailed installation instructions and full technical support by phone or online. Harness comes completely loomed with automotive grade split loom. We use all GM grade connectors.

Installation consists of simply laying out the harness on the motor, plugging in the various devices. Each harness has 3 feet of reach from the rear of the engine to the ecm, with an overall length of 5 feet. 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 TPI engine into any vehicle. Harness must be used with 01227730 ecm (speed density computer) and the correct prom chip with VATS removed.
