I am a new owner......there are three wires in engine compartment (white, black, yellow) not hooked up to anything. Anyone have any idea what they are for? I posted an earlier question regarding why many of the indicator lights don't light up when in use - example 4 wd, forward and reverse, pto, etc. The response I got was that if my tractor isnt equipped, they won't light up. The turn signal indicators, parking and pedal brake, do light up. I was wondering if these three wires might havesomething to do with dash indicator lights. Thanks for your patience and help! I suppose I should call the dealer but this message board has answered load of questions for me already.
