This allows you to raise/lower the top while the engine is running.
In the fuse box, remove relay G21, jumper pins 1 to 2, and pin 8 to ground.
I drilled a small hole in the case and attached the ground there because I could not find a ground on any unused relay sockets. G21/pin 7 reads ground when the key is off, but reads 40ohms when the key is on.
