Question on Boxster Cruise Control

From experience I think it would be a good idea to familiarize yourself with the clock spring before re-installing the steering wheel.
While re-installing the steering wheel I was concentrating on lining up the steering wheel and forgot about the clips on the clock spring and broke one. The clock spring is a pretty simple devise comprised of three components. Two loosely held together plastic pieces with a ribbon of wire inside. Two wires for each electrical component in the steering wheel ie air bag, horn etc. With tiptronics, inside there is a ribbon of 7 wires. One not used.
On the front there is a metal clip with a spring. The clip is engaged when the steering wheel is removed, locking the clock spring in place. So that it doesn't rotate. If you release the silver clip the clock spring will rotate 4 turns. There is a white arrow on the front half of the clock spring face and a black arrow on the back half. You want the arrows to line up with each other at the top and be able to turn the clock spring two turns in either direction. For a temporary fix I super glued a piece of 7/8"
long plastic irrigation hose over the broken clip. fits perfect on the clip and through the holes in steering wheel. see picture.
On the back half of the clock spring you'll find a plastic tab about 1 inch wide that protrudes about 10 mm out the back.
This tab turns off your directional lights when the steering wheel comes back to center. The tab should be installed just deep enough to disengage the directional. You need have a little clearance. How deep you locate the stalk on the steering column will determine this.
Once I had everything back together I realized I had also broken a wire in the clock spring. My horn would only work when the ignition was off, and tiptronic wasn't working. The wires in clock spring are color coded so you can check for broken wires with an ohm meter except for the air bag. The air bag has what looks like a resister inside the yellow connector. Hope this info helps someone else.
