Our harnesses are built for simplicity, not shortcuts. These are true plug-and-play wiring harnesses with no cores or extra wiring needed. Every single wire is point-to-point continuity tested before it leaves the shop, so what you install is exactly what was engineered.

Our main engine and transmission Pro Series harnesses come as one clean, methodically tucked piece. You get factory-tight fitment that looks as good as it runs. No guesswork and no wiring gremlins.

Best of all, it is backed by our Turn Key Engine Start Guarantee: wire it in, turn the key, and it starts. That's the standard.
