You will find a transistor / heatsink assembly on the rt side under the facia behind the knee shield (at least that is the book's description)
If you have a diode check function on a multimeter check all three legs/pins to see that it is about .7v one way and open or OL the other then check for varing voltage on yellow of heatsink assem. which is the throttling control for the transistor, should have batt level on the green and there will be varing voltage output on the Brown/Wht wire. All this measured on Volts DC ref to grd.
