Here is what I got from PCA tech. Food for thought!

"The rev limiter is in a box located behind the fuel gauge. I could not find a part number for it, but it may be printed on the box. It has four wires: red, white/red, brown, brown/red. It works by grounding the fuel pump relay. The circuit is part of the 78 wiring diagram in the factory manual. They call it a speed switch. It cannot be adjusted that I know of. It can be disabled, by disconnecting the brown/red wire. I think all cars are the same on this.
