“If I didn't know it was an aftermarket harness, I could say this is an OEM harness.”

BUILT BY AN ENGINEER, ON A REAL BENCH
MK6IX started with retrofits on my own cars. With a background in electrical engineering, I design each harness from factory wiring information and real-world testing, with verified pin configurations for every application.
Every harness is assembled by hand in Toronto for its specific VW or Audi application. Nothing is dropshipped and nothing is generic.
