Welcome to BP Autmotive!
Welcome to BP Automotive! We specialize in Standalone Wiring Harnesses for GM Gen II LT based engines, Gen III, and IV LS based engines and transmissions. We also specialize in custom harnessing for your s10 V8 LS Swap, your LT1 24x Conversion, New Replacement F-Body engine harnesses, and full custom built to order stand alone engine management harnesses. In addition to the hand building of new wiring harnesses, we also offer a rewire service for your existing harnesses, also you will find other components and kits including PCM programming. Be sure and check out the swap parts page where you can find the little odds and ends you need to finish your conversion, or to find miscellaneous adapters and pigtails!
We offer a premium wiring harness; we only use OEM terminals, connectors, and seals, no knock off or used connectors! We use GM color coding, not just a small variety of colors with our own color codes- this is something you will see a majority of our competitors doing. Don't trust your high end investment to anyone else, we are your one stop shop for LS1 and LTX standalone and custom engine management harnesses. I personally build each and every new harness that is built, this ensures the highest quality imaginable, the reliability that you demand, with the looks you want! Be sure and visit our commitment to excellence page to learn more about us and what we do to go above and beyond. You will also see the craftsmanship that is out there, showing you the downfalls of many harnesses on the market.

Don't forget to check out the Accessories page for any needed accessories! We also build a full line of Extensions, Adapters, and Add On Harnesses too!

At the current time harness build/rewire times are 4-6 weeks.
