The "Turn-Key" Connection: Full Harness Conversion & Performance Tune Package
*You Must Send in Harness and PCM/ECU for Service*
Stop struggling with wiring. Start your engine in 5 business days.
The biggest hurdle in any LS swap is the electrical system. Why buy a harness from one guy and a tune from another?
At Myatt Motorsports, we offer the ultimate "One-and-Done" solution.
Send us your factory GM engine harness and your PCM. We don't just "re-pin" it—we transform it into a professional, standalone, plug-and-play system specifically calibrated for your exact build specs.
With 29 years of mechanical experience and over a decade of specialized LS tuning, we ensure your project doesn't just start—it performs.
WHAT’S IN THE BOX:
Full Standalone Harness Conversion: * Clean, professional integration of your factory harness.
Brand new Relay & Fuse Block integrated.
Labels on every major connector for a "No-Guess" install.
High-temp, professional-grade looming.
New OBD port and Check Engine Light w/3ft of wire
Custom Performance PCM Tune:
Full Standalone Calibration (VATS, EVAP, Rear Gears, Tire Size, Rear O2 Deletes).
Optimized Spark and Fuel maps for your specific intake/exhaust.
Performance Cam Scaling Included (if applicable).
Transmission calibration for 4L60E/4L80E (Shift points, firmness, TCC).
The Myatt Guarantee:
5-Business Day Turnaround: The fastest in the industry.
Direct Tech Support: If you hit a snag during the install, you call the man who built the harness.
WHY CHOOSE THE COMBO?
When you bundle your harness and tune, we test the integration before it leaves our bench. This eliminates the "finger-pointing" that happens when you buy parts from different vendors. We own the electrical system from start to finish.
HOW TO GET STARTED:
Add to Cart & Checkout.
Fill out your engine, cam, transmission, gear, tire size, etc details.
Wait 5 Days: We perform the conversion and the flash.
Turn the Key: We ship it back via USPS Priority. Plug it in, hook up 4 wires, and hear your engine roar.
