The handlebar switch can be mounted on the RH side of the bars to the brake perch without any problem, the technician will need to swap the yellow and the green wires in the black three-wire connector of the handlebar switch wiring in order to keep the buttons working in a corresponding order (top button-pumps / bottom button-dumps) or they will be backward. We also offer a crossover cable that can be used instead of swapping wires. This can be found here: https://www.legendsuspensions.com/product/handlebar-control-crossover-cable/
