    Someone will correct me, the five wire servos, didn't I read they ran off a separate ECU? Or did I dream that.

        Are you spare wires
        One black yel bullet
        An other 2 one brown one black both live in same connector ?

        If so you need a 3 wire servo
        5 wire servos also need a contrôlér but 3 don't 🙂

                          Can you not just get the CDI that will do both the ignition and servo.

                          I run a Zeeltronic on mine, which is hands down the best bang for buck in terms of performance. Gives you complete control over the YPVS operation.

                            If you have a 5 wire loom, then YPVS is controlled via the single CDI unit, you should be looking for a 3RM -?

                            Seperate Servo controllers were one year only on the DT125R back in 1988. 3 wire looms,

                            Keep it real
