the kill for the brake is easy.... its grounding output- you should be able to take the wire and ground it to bare metal to shut off the engine-
you need to make sure you get all the correct wires tagged from under the steering column- if these arent correct, you will not get the desired results. did you happen to install the hood pin switch to kill the remote engine when the hood is opened?
you might be able to go to AUDIOVOX website and get the wiring diagram for your specific vehicle so that you can verify that you did get the correct wires. Good Luck!
