It is a proximity sensor from WW Grainger. 12 VDC NPN 3 wire.

I mount it so it senses the bolts on the rear brake rotor. Works great. I use 6000 pulses per mile.

I just order the other wheel, cover and spring from the RT Splitter box. I also drill out the splitter box for the curse cable.

Good luck
