## Description

Review: MARCH 2026!! Purchased for my 2003 suburban. I was getting a "Controller Unlocker: Timed Out" error while trying to tune the truck with HP Tuners. I removed my PCM and used this harness to try and get my laptop to communicate with the PCM and it worked perfect. Other reviews talk about wrong pinout and the power supply not working. Mine was pinned correctly and the power supply that is provided worked flawlessly as well. If you are having issues with HP Tuners try this. You probably have some interference in your wiring harness causing it not to work. 10/10 would recommend this harness!
Review: Muy practico!

I was a bit hesitant after reading a few negative reviews, but the unit I received works perfectly. I checked for the issues others mentioned—Pines in wrong order, and bare connections—and mine had none of those problems. Build quality seems solid, and it's doing exactly what it’s supposed to. Glad I took the chance on this one.
