Your switch for kick down may not be the correct type. The kick down switch controls two separate circuits with emphasis on separate. In the normal position, the operating circuit switch is closed and the kick down circuit is open. When the kick down button is pushed all the way, it opens the operating circuit and closes the kickdown circuit. You will need at least a double pole double throw switch to keep the circuits separate from each other. The bad thing about that is that it's a three position switch so it would have to be clicked through two positions for kick down and then back two for normal operation. If you left it in the mid position it will turn the system off. That might not be a bad thing though. It would act as a lock out switch if you are trailering or in the steep hills.
