WOW what I know about wire color codes is this. The yellow wire usually is for the rear light. The blue wire is generally a common wire, probably for the smoke unit, but it used for headlight, rear light, or other functions, but like I said maybe the smoke unit since it doesn't work. The gray wire normally is the ground wire for the motor.

Scott,

I cut those wires and run without smoke, but I do have a photo showing the grey wire on the right:


That's lead and epoxy filling the former smoke unit.

Went looking for the left side (photo), but none show the left wire:

Already clipped and tucked under, sorry.

Your model has an on/off switch in the cab.  The wires leading to the switch are blue and pale orange.

Hope that helps a little.

Regards,

Jonathan
