The wires connect to a micro switch which is a top position sensor. In the movement position, it's open--so that the motor runs and the dash lite is lit. At either end of the tranmissions travel, it closes. You want to fool the system into thinking that the top is either open or closed all the way. So you jump the connector as shown below.

Hey guys,
I'm having any issue here and I'm a little confused. My top dash light won't go out when I put the top up and clamp down the shell but it turns off when the top is totally down. What is the issue? I can't find any transmission sensor and I'm a little confused by "jumping or shorting it". How do you do it? This light is driving me crazy. Any help would be appreciated!

Jumping the pins only applies to manual tops. Probably a bad idea if your top is still powered. You either have a bad transmission micro switch, or one of the top latch switches.

Hey Particle,
Checking things out. Went over the latch switch and it looks ok. I check for a B-pillar switch which my model (2002 Boxster S) doesn't have. Can anyone confirm this? From what I read, this switch sends a signal to the relay that the top is closed. I'm still not sure what the top transmission switch looks like. I did a search and haven't come up with a photo...

There are microswitches in the latch. Seems like one of those switches is your problem, or a couple solder joints within that latch.

Dj could also have a transmission starting to go out. Mine did that for a while before it finally failed. The left side where the switch is located could have a gear problem while the right has enough push to get the top to the point where you can close it. At least with mine it started working erratic jerking and such. It took mine about a year to finally go once the light quit working as it should

Hey Ben,
Interesting stuff. This sounds like my issue because it makes a different noise than what I'm used to on the side of the transmission. It's kind of stuttering slightly to close. Thanks! Is the transmission switch located on or close by?

I think that the change in the design was in the 2000 model and later.
The 2000 and later models have one switch in the latch, a different relay module, and the transmissions are different with the 'B-pillar' microswitch internally rather than on the B-pillar.
Here's a copy from an old post that shows the transmission and microswitch location.

Hey Piper,
Thanks for the Vid! It's ironic, I discovered this guy this week. He has a lot of good stuff on his channel. I check the latch and there was a little corrosion but working. Funny, it only had one switch, the one that drops the windows. Again, mine is a 2002 Boxster S.
