Kwikee step control

Not sure but here's my recollection. Sometime in 99 Kwikee changed how there controllers worked - the old ones operated with a magnetic door switch that was "normally closed" and the new ones operated with a door switch that was " normally open". The post 99 controllers often came with the revised door switch but not always - no big deal as the new door switch was readily available from any parts house and not very expensive. If all that's correct then chances are controller may work but you might have to buy switch.

You should contact the new owners of Kwikee - PowerGear - probably have to write as I have read that they never answer phone.
