To some, the very thought of re-wiring a rig conjures up images akin to climbing Potato Salad Hill at full throttle in a TJ on 37s. We'll admit it, some of us are afraid to do any of our own electrical work-so very afraid-but thanks to companies such as Painless Performance Products, the guesswork and the voodoo has been removed from the equation, making any wiring job a whole lot more palatable. Painless offers products such as complete conversion engine harnesses, with or without computers, for those of you who want to put an LS1 crate motor in your K-5 Blazer, for example. Painless also makes a direct-replacement Jeep CJ-7 harness, which also happens to be one of its best sellers, in addition to its universal harnesses and miscellaneous electrical hardware that can be used to rewire any project.
Painless invited us to its headquarters in Forth Worth, Texas, to take a look at how it puts together the most user-friendly wiring systems in the business. Painless employs about 71 employees and has been around since 1990. Dennis Overholser, Executive Vice President and co-founder of Painless Performance Products, graciously opened his doors to us and took us on a guided tour of the Painless manufacturing facility.
