Thank you for your reply. Yes apparently somebody switched it out and either used a hyster switch or a generic one. The hysters from what I can tell swap and are a perfect hook up. I believe it just plugs in but havent really looked at it see how to get into it. I thought it was just a couple of screws to get the plastic off to get into it but apparently it is a little more involved and hoped somebody knew exactly how to do it. Searched online and have had no luck so far. Thanks again for your reply
