If it's a ground problem, can I use a ground wire somewhere to make sure that it's not my connection to the chassis that is bad!? thanks for you help !

That is correct (it's actually >25 mph). Just to clarify, the on/off switch is the one before the resistor and the set switch is the one after the resistor.

By the way, I believe that you are the first Canadian trying this.

For a ground, The bolt that you posted the picture of is a great ground point. You can strip about an inch of insulation off of the wire, wrap the wire around the bolt (under the washer) and crank the bolt back down.
