The ABS requires a secret handshake. You flip the switch on while the bike is on, wait for the ABS light to blink twice, then you turn the switch off. after that you're going to see a constant blinking from the ABS about one blink a second. ABS is now turned off. To turn ABS back on you have to turn the bike off, then turn it back on. I ended up going with a momentary switch since it's easier than a toggle switch. I bought the stainless steel one on Amazon. The switch has 3 wires but I only connected two since I don't need the light.
