I installed this hack a few weeks ago and finally found some time to make some instructions for everyone. It is the same as the kit that shows up on eBay every few weeks , but will cost you about $40 less. The site with the original instructions disappeared, so I have figured out how to do this and made a PDF you can download.
Basically, this hack enables the use of variable intermittent wipers in your 986 Boxster. It allows you to use a dash mounted dial to set your wipers to wipe at an interval between 4-30 seconds. This is a great addition to any Boxster especially if you drive in the rain. It is completely OEM and fully reversible (depending on a few choices).
You can get the instructions on my website which can be found here:

This hack works great, and I hope you enjoy it!
