The Jaycar Speedo Corrector is wired into the RX3 the same way as the SpeedoDRD unit from 12oClockLabs.



The RX3 employs a sending unit on the front wheel which uses has three wires. One wire contains 12V DC, which powers the sending unit. The other wire is a ground wire. The third wire transmits pulses from the sending unit to the Siemen's speedometer.



We would tap into the three wires on the opposite side of the connector, at the wires that lead to the speedometer.



One wire feeds 12V DC to the speedo corrector, and one wire feeds the ground connection. One wire feeds input from the RX3 sending unit to the Jaycar unit. One wire feeds the corrected signal from the Jaycar unit to the speedometer.

The Jaycar unit has convenient holes in the housing, so we could attach the unit under the dashboard with zip ties.
