Answer
Randy,
normally the solenoid wires go to a small relay
box under the seat and from there to the other
circuits including the starter button.
You would have to spend alot of time with a
shop manual or circuit diagram to rewire this.
If it starts by connecting the solenoid wires,
as you mentioned, why not just get a switch
or button and connect it to the solenoid directly?
Just ground the b/w wire and hook one side of the
button to the solenoid r/w and the other side
to fused battery power.
