One thing your gonna have to do is possibly get a new cable that goes to the throttle body....unless the explorer is a 4.0 and you have a 4.0. The cable is engine specific.

Then you got to replace the clockspring and wiring. Replace buttons. and then the wiring.

OG/LB speed control indicator lamp ground (goes to instrument cluster to activate "speed cont" light

GY/BK Vehicle speed sensor

TN/LB Brake Pedal Position Switch (to deactivate when you hit the brakes)

LB/BK and DB/OG wires to the clockspring wiring for the switches

GY/YE Ignition source

BK/YE Brake pressure switch (goes to switch on master cylinder, you probably don't have it so I would just splice that to the GY/YE wire)

BK ground
