REPLACE YOUR TIRED OLD CARB WITH FUEL INJECTON AND GET BETTER MPG

New TPI stand alone EFI wiring harness .  Manufactured by Larry's Electric.  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.  Fuel injection is well known for improved gas mileage over carbs, and with prices today its well worth it.  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.  With over 15 years experience, if you got a question we will answer it, and when you call you actually talk to someone who makes the harness, unlike other companies.  We use only GM color codes for easy trouble shooting.  Our harnesses come completely loomed with automotive grade split loom and all wires are coated with a flame retardant coating.  Each terminal is machine crimped and tug tested, splicing is also done by machine and followed up by hand soldering.  We use all GM grade connectors. (no cheep knock off's).  Installation consists of simply laying out the harness on the motor, plugging in the various devices, and hooking up only 3 wires, ignition power, battery power, and your fuel pump power.  We have provided plenty of room for placement of the computer, 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.  As mentioned above this auction is for a new harness.  Harness must be used with 01227730 ecm (speed density computer) and the correct prom chip with VATS removed.  The ecm and prom chip are availible from us for an addional cost.
