The customer gets a pig-tail harness with their SBx unit. This option allows the customer to freely access the signals from within the SupabBrake module via an extra harness. If your bike has a 3 wire system then there would be the +12V, stock brake output, modulated brake output(from SB) and ground available. If a 2 wire system then only stock brake output, modulated brake output from the SB 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 etc.
