We HIGHLY Recommend purchasing new injector and coil pack sub harnesses, most OEM sub-harnesses are worn from use over years and sometimes will not work properly, dont waste valuable time trying to diagnose and fix wiring problems from your old factory harnesses.

Reviews

  1. Highly Recommended

    Posted by Unknown on

    I was doing the wiring swap on my own but couldn't get the car to idle. So i decided to buy this harness it installed extremely fast you couldn't screw it up. Just about everything worked properly but my tach is off just because a KA tach can't read a Coil on plug signal properly. I would recommend this to anyone.

SO THANKS GUYS!!!! i will be puting the word out there that WIRING SPECIALTIIES IS THE WAY TO GO!
