This mod allows the driver to raise or lower the top while in motion
without having to pull the emergency brake.
The instructions are as follows and work on 986.616.199.00 relays; model years 2000-2004.
This
can be done on the 1997 -1999 relays also, but the pinouts are different and this guide doesn't apply.
1. Pull the relay out the relay board. It is just above fuse box and is the biggest relay there.
2. Pry off relay cover with small flat jeweler's screwdrivers along the long side of the relay, being careful not to damage the circuit board inside. This picture shows the four pry points and the pins to bend.
3. First tin and then solder a small wire to connect the two points shown in the photo. The wire you use must be small enough to rest against the circuit board (insulated of course) and will allow the relay cover to slide back on.
4. Bend pin 15 and pin 18 out of the way. I bent pin 15 outwards so it extended slightly past the edge of the bottom of the relay. It makes no contact with anything else. No issue there. Pin 18 folds flat against the bottom of the relay itself.
5. Reinstall the relay. Even with pins bent it still goes in only one way.
6. Start the car, disengage the handbrake and test for operation.
7. Be careful how you use it, as you have now bypassed all of Porsche's safely features on the relay. With this hack completed, it is possible to raise or lower the roof at highway speeds which will wreck it. Limit roof operation to speeds of 20 -25 mph.
I've been running this mod for 2 years now with no issues.
