However, for those that may want to accomplish this mod on Kwikee steps it should be noted that prior to 2/99 kwikee used a NC door switch and it is still available, part number 905312000 and available from American RV Company $12.00 (and others). Probably can be mounted on existing small door switch using existing single magnet or added to doors independently. Just a thought.
