The customer gets a pig-tail harness with their SBx unit. This option allows free access to the signals from within the SupabBrake module via an extra harness. If your bike has a 3 wire system the switched 12V, modulated brake output and ground will be made available. Stock brake signal also available upon request. If a 2 wire system then only stock brake output, modulated brake output and ground will be available. No +12V for a 2 wire system.
This is very useful if you need to power up additional third party external LED lights or such LEDs as what is common on a luggage case or license plate LEDs or (dummy LED load/camera/GPS only for 3 wires systems). The splice (solder) is made on the internal PCB itself where we have allocated the proper soldering pads. The entire device, like all Supabrake products is potted with automobile electronic grade epoxy for a waterproof connection/seal. From your point of view, all you need to do is install the SupaBrake like you would normally, and terminate your extra device with the mating connector which we ship with the product.
The extra harness will be terminated with a 3 or 4 positions Amp Superseal 1.5 Series waterproof OEM grade connector. Length shall be no less than 6 inches. Wires shall be 18 or 20 AWG. Consult your service manual for allowable spare current on the tail light circuit/wire/connector. Not recommended for heavy loads such as grip/seat warmers. Note that some of the newer bikes (especially) the BMW limit the spare current available. This is due to their real time monitor over the CANBus. For this you'll need an extra driver. We offer a solution for this. Please contact us for more details.

By using this along with Bernard's knowledge I was able to leave my factory wiring in tact and still utilize the features of the Supabrake 2 with my stock tail light and the additional lighting installed in my top box with a quick disconnect when the box is not in use.
