Why Our LS Swap Conversion Harnesses Beat the Cheap Imports Every Time
1. Built Right the First Time
Cheap harnesses might save money up front—but they’ll cost you in the long run. Our harnesses are hand-built with high-quality wire, heat shrink, and OEM-style connectors to ensure your swap works right—the first time.
2. No Guesswork – Just Plug and Play
Generic imports often need modification to even fit. Ours are tailored to your exact LS engine and vehicle setup, minimizing headaches and wiring issues during installation.
3. Tested. Reliable. Track Proven.
Every harness is tested before it ships. Whether you’re cruising, racing, or off-roading, our harnesses are built to handle real-world abuse and engine bay heat—something the eBay specials can’t promise.
4. You Get Support – Not Silence
With cheap harnesses, you get zero tech support. With us, you’re not just buying parts—you’re getting knowledge, experience, and help when you need it.
5. Built by Enthusiasts, For Enthusiasts
We’re not a factory overseas making 10,000 at a time. We’re builders who know what it takes to make a swap clean and reliable. We treat every build like it’s going in our own car.
How the process Works
Once we receive your harness, we completely strip it,
We remove pins, wires and connectors that's not needed,
We add a fuse block with 2 relays, we add a obd port and LED check engine light with 3 feet of wire so you can mount them in the cabin.
We solder and heat shrink all joints, we then top it off with high temperature flame retardant wire loom for a stock looking appearance.
Harness Conversion is a simple 3 wire Hook up.
We include our instructions for installing, (not knock off copies of someone else's)
