I had the option of a joystick type thing or remote. I opted for the remote option. The remote has 2 buttons, open or close. Press and hold either for 5 seconds.I like the idea of being able to open and close the valves before getting in the car obviously depending on where i am.
The joystick doesn't really suit being in the interior. Also I'm not willing to drill holes in my interior to make it look flush.
Essentially with the install. 2 very long wires plug Into either the remote harness or the joystick harness if that makes sense?! The harness then needs to be soldered somewhere to power itself.
