Okay, call me an annally retentive engineer, which I am. But, it's impossible for me to understand how light bulbs that are not lit most of the time while the cruise control is in operation, have ANYTHING to do with cruise control operation.
I bought in on this suggestion without thinking about it several years back before I thought about how ridiculous it is.
So, please explain how a resistance that is not in any circuit has an effect.
Have a great day,
