Convertible Top Control Unit

So my top will not go down at all. Replaced the top switch (not that) checked the relay and that was fine. But I was wondering if anyone knew where to find this top control unit on a 1999 Porsche boxster? I checked up in the dash in the drivers side footwell and didn't see anything that looked like it.

Quite possibly your parking brake switch. Search for a diy bypass.

Not necessarily. Does your parking brake light come on in the dash when you pull the handle?

Yes, it seems to only go down when it's in the 60s but doesn't do anything once it reaches 70 and higher.

Yeah I think that switch is definitely going bad, I gotta mess with the latch before the motor starts going. But I still don't understand why on days where it's 70 degrees I wiggle the latch and nothing happens at all till it cools down to the low 60s.My only guess would be the top relay.
