Default performance chip

I have a surge performance chip purchased from auto direct save.

They don't have pictures for the proper connection to the the engine and have not been helpful as to the proper installation (at all).

I was hoping someone on this forum might have experience in this area.

Well John I can tell you that those are probably a scam but they go in the 5v supply to the TPS as I have read. But everyone says it makes your Jeep run rich which wastes fuel. I have no first hand knowledge though.

Take it back and get your money back. Those chips do absolutely nothing for the 4.0.
