all so the isc moter is not wired correctly. i found this out the hard way when i hooked it up and the moter went to 5,000 rpm untill i shut the moter off. just to let you know. the yellow/blue is the + for the isc motor.the yellow/black is the - for the isc motor. so the yellow/blue needs to go the the green/white, and the yellow/black goes to the black/yellow. i compaired the 86 to the 88 wiring diagram and found this out.
