Hey fellow 986 owners,

A friend and I came up with an easy-to-install device that allows one touch top operation. We made two of these for our own cars and we are considering making more of them if anyone is interested in buying one. The unit allows you to raise or lower the top by touching the button once. If you want to stop it, you touch the opposite button. You can then start it again in either direction by pressing the desired button.

It doesn't have speed sensing, so if you want to operate the top while moving, you can do the pin 18 hack on the top relay, which is what we did. This doesn't prevent you from trying to operate your top at high speed, but we don't think this is a big deal. It's pretty easy to know when you're above 25 MPH or so. Also you'll still need to pull your parking up a click in order to operate the top. This can be defeated as well, if you like, but again, you have to be smart about it.

The installation is easy; it goes right behind the switch. You unplug the switch and install this between the switch contacts and the connector. That's all there is to it- it takes maybe 15 minutes to install, if you take your time.

Based on what it cost us to build these, we'd be able to sell these at less than $100 each.

Anyone interested?
