9. Doug located the ECM (arrow) and routed the supplied wiring harness for the tachometer and speedometer up to the fairing from the ECM. With the tachometer and speedometer, Doug started with the supplied tach wiring harness (TWH) and cut the white/green wire from the ECM and soldered one end to the white wire on the TWH (A). The pink wire from the TWH was tapped into the other end of the cut green/white wire (B). Then Doug heated the shrink-wrap for the newly soldered wires and moved on to soldering the speedo wiring harness (SWH) to the ECM.
