I think it is built into the stock ignition module. But possibly it may be piggy backed next to it and maybe you could just unplug it and use a jumper wire ???

It depends on what you have. On my 525SC with a TB IV ignition, there was a separate box that was the rev limiter. You could just get a standard 454 mag wiring harness that goes from the module to distributor and eliminate it.
It will depend on the serial number for your engine and what ignition you have.
If you have this set up, you can do as I said.
