​Cars has always been fascinating to us. As a kid the owner recognized early on that you can tailor your car to match your personality. He knew the it can be done with a simple or complex paint job or modifying the engine . Growing up in a small town his father taught all about the details of a car and truck . His father was never shy from having him hand tools while he worked on cars and having him getting his hands dirty by assisting with building motors and any and everything else that the car or truck needed at that time .These fond memories and lessons has influenced us to start the harness business .


The sound of the motor gives a car its voice and the mechanics of that motor is what's most exciting when it comes down to cars. With our harnesses we want to assist you with giving your car it's voice .


We are proud to offer you high quality standalone harnesses. It is the expectation that with our harnesses you will be able to make your installation neat and easy for the performance shop that has a large amount of experience or the person who has zero experience with wires. With our simple three wire hook up your motor is ready to roar its voice by cranking up.

Check out our website and see the products we offer . We are sure you will be impressed because your car will be impressed with our harnesses.  We here at Lab Rats Performance thank you for trusting us with business and time.
