Color Coded ECU Patch Harness

At last! Here's a way you can install items that require wiring to your ECU, without hacking up your car's wiring. Just make your connections to the patch harness, then plug the patch harness into the car. No more hanging your head upside down in the footwell; you can do your soldering work at the comfort of your dining room table. And later, if you want to remove your modiciations, it's as easy as clicking the harness free.

Unlike the generic Japanese harnesses, our color coded harness has frequently-used wires -- injector signal, 12 volt power, ECU ground, RPM signal, throttle position, speed sensor, airflow signal, and constant power -- clearly marked with color wire and slightly longer lengths, so you can easily identify and work with them.

Do yourself the favor of buying the harness. You'll thank yourself later.

Available in two models. One fits all 2002+ WRX except the STi model (see top pic). The other fits the STi, plus turbo Forester, turbo Baja, and 2005+ Legacy turbo models (see inset pic). The 2.5 one costs more because the plugs have four rows of wires, and it's quite time-intensive to build.
