I believe there are microswitches associated with the flaps. There is another option for you. Pelican Parts sells the Porsche shop manual for this convertible top. It would probably have the answer and the procedure for calibrating the top. It's $280 and I have been meaning to buy my own, but I already spent $3000 at the dealer to get my top repaired (cables that pull the clamshell release broke - $1000 in parts and $2000 in labor) and I am hoping to never deal with the top again!
