These EBay and Amazon harnesses/injectors are killing yalls pocket book! If they worked I'd be all for it, but they just simply don't.

I wish I could tell every single person that does a swap, wiring harness, injectors, o2 & map sensor are the most important part of the equation! Don't skimp out!

Just do it right the first time and let's get these money pits on the road!! 💯
