Dennis, my understanding is if you have a CAT, you need to use the Rev limiter that will kill fuel.
Tony,
It is a six prong connector but only four wires. Below is a diagram of the colors and the terminals where they connect:
Brown/Red . Brown
Red and . Red/White
The car runs great without the Rev Limiter, just think I should get this buttoned up some day as this is a safety feature.
