Get your LS1/LS2/ LS3/LS7 Wire Harness Today.
If you are searching for a wiring harness to run a GM fuel injected LS power plant you are in the correct place. Any GM engine wire harness can be tailored for you here, whether it be an LS1, LT1, LS3 or LS6 wire harness. We also offer a wire harness modification service. This service requires you to send in the factory harness, and computer, we re-work it for a set fee, then send it back.
Computer programming is just as important as the wiring, we spend countless hours matching up the correct calibration, for your specific application. If you are in need of only the computer program, let us know, we will help out any way we can. We also cater to Ford wire harness modifications and conversions.
When finding parts, and pieces for your engine wiring or vehicle conversion, its always best to get absolutely everything you can. If the salvage yard offers you the option of a parts buffet, then specify that you need: The engine wiring, LS engine, ECM, pedal, TAC module, transmission controller, all accessory brackets, with the belts.
More specifically you want a full pull out engine, if you plan on going with factory brackets, this is the best way. Even if you don't ultimately end up using the factory brackets, you can always sell them on Ebay or CL to fund the new brackets.
By saying the word full pull out engine, you are requesting to have the engine / drive-train pulled out of the donor vehicle, without the salvage yard picking over it. Most salvage yards break down the LS1, LS6 and LS3 engine to make way more money, a la carte style.
The text below explains three specific classifications that we build by. You will only need to choose one, unless you have more than one vehicle. E-MAIL US.
Custom Stand Alone Wire Harness - This is the one for you if you didn't receive the fuel injection harness with your engine. New harness built from scratch, color coded then configured to fit perfect. Every wire harness comes complete with new wire, genuine GM connectors, and terminals. We also crimp all terminals using GM tools; then solder the terminals.
Modification Wire Harness - You must have the harness off of the donor LS6, LS2, LS1, LS7 engine, undamaged. We then re-configure, and tail out what needs to be used to run the engine and transmission correctly. The wire harness also has a new look to it, when you get it back.
Conversion Wire Harness - If you have a stock TBI fuel injected truck or a S10 or Sonoma with a Vortec 4.3L or a 2.2L and want to change the engine to an LT1 or LS1. Speed Scene Wiring will marry the two harnesses together to make one.This is the only way we recommend. Due to the fact that if the harness is not converted the dash, four wheel drive, ABS and on board computer will not function, like GM engineered.
