How do I disable the Speed Sensor to the relay on a 1999-2004 996 Cabriolet?
On a Boxster you bend Pin 18 of the relay, but on a 996 you can follow these directions taken from a Renntech.org post.

Ok, do this at your own risk...
Here is what we did on a MY 99 Cab:

"Thanks Loren, It worked I now can raise and lower my top while moving, just click the e-brake to the 1st click and it works!

Now, as for how it was done:
1. Park your car and set the e brake. With the convertible top down start raising the convertible top. First thing that happens is the convertible top compartment lid lifts and moves all the way rearward, keep raising the top until the convertible top compartment lid just starts to move forward. Then interrupt the closing operation.

2. Remove key from ignition THE CONVERTIBLE TOP MUST NO LONGER BE ELECTRICALLY OPERATED IN THIS POSITION.

3. There are right and a left tension cables that goes from the rear of the convertible top on the right and left sides to the right and left sides of the deck under the rear of the convertible top. These 2 cables are 4 inches long and they keep the rear of the convertible top from flipping up. They snap off where they connect to the deck, just push to the side and they will pop off the ball.

4. Lift the rear of the convertible top (the window part) all the way up until it is vertical and have someone hold it there. Now the deck is exposed. You will see 4 black plastic rivets that you just pull out (you can use a small screw driver) and then you can pull the panel rearward to expose the convertible top control module. its the large silver box on the left side of the car mounted on the vertical wall just behind the pop up roll bar, with the 3 separate connectors going into the bottom of it.

5. The connector all the way to the left with all the small wires going in it is the one that you want.

6. Do not disconnect the connector from the control unit, just find the GREY/ PINK wire and cut it 1 inch before it goes into the connector and put a small piece of black tape on each end and then put a piece of black tape around all the wires.

7. Put the panel back up and push the 4 plastic rivets in and lower the rear of the convertible top that someone was holding and attach the 2 cables to the deck.

8. Now put the key in the ignition and raise the top all the way.

9. All done, now take out for a test drive. While moving at 10mph raise the e brake 1 click so the e brake light comes on and lower the top. When done release e brake all the way.

Please note, This is something I did to my car because I wanted to. I can not be responsible for anything that happens if you do this to your car and don't ever put your top up or down while going over 20 MPH."

Note: If you want to do this and have a different model year you should post a message (and someone will check for you) as some wire colors have changed over time.
