Stretch Cord
3 Core Wire

Three conductors? Why? Let's say you want to mount your transbrake button and your line lock button on the steering wheel... both buttons need power supplied to them right? The SC3 has 1 super large 12 gauge wire to bring power "up" to the both buttons, then use one of the 14 gauge wires to bring the transbrake button signal "down" and the other 14 gauge wire to bring the line lock button signal "down". This is a lot cleaner and less expensive than running 2 coil cords! Medium Red vinyl jacket stays clean after years of use.
