Stand Alone Wiring Harness LS Series Engines 4.8 / 5.3 / 5.7 / 6.0 Modification of Factory Harness:

This is sort of the junk yard special budget option. If you get your engine complete with harness, Sho-Me Speed will use it as the starting point for a custom harness for your application. Adding an LS engine to a Hot Rod requires a few simple connections to things like power and ground. With this option, We supply just the basics to make the engine sensors work with the computer but have very little integration to the vehicles electronics. That means things like gauges need to be handled independently. Sho-Me Speed custom stand alone harness's include all of the needed fuses and relays The harnesses are simplified down to separate one wire hook ups for battery power, key on power, fuel pump power, check engine light out put (if requested), and even the cranking or starter circuits. We will even supply any needed sensors and a PCM (new or remanufactured depending on year) that is flashed with the correct software program for your engine and ready to run. We will set up the computer for the transmission, axle and tire size used in the vehicle so that it will shift correctly and will accurately know the vehicle speed. We will also set the computer up so all of the emissions, EVAP, VATS and other unnecessary sensors that are not needed.
