This package doesn't use Technic's harness. We make this one ourselves. If you were going with the 6-channel, rear-speaker-upgraded option, then we would include a modified Technic Stereo harness and you would have to pull the radio.
This routes signal to the processor location, and door and underseat speaker wires to the amplifier location.
