The idea for these harnesses is to have people avoid cutting up their original harness when running aftermarket gauges as their new gauge cluster. It should make things easier for people to tackle their own wiring, just like a car stereo adapter. One thing to remember is our cars are getting older and parts are harder to find intact. With Tight Fit Fabrication S13 Wiring Harnesses you will be able to plug your OEM cluster back in if you want without any issues.
