HFS-2 Help needed.

[ZiF_k23]

Hi guys.

Not too sure if I'm posting in the correct section. I have recently purchased an Aquamist HFS-2 kit used. I am currently trying to install it on a 2006 model 1.8t 20V Polo Gti. Initially I did a test run connecting it to the injector harness. For some reason, on idle, there was a continuous stream being pumped. Kit was removed for a a few weeks till i had some time to redo everything. I need some assistance as to the setup of the controller and also to find out about the switch. There is a red wire which is not connected inside. Is this supposed to be this way? Does the switch light up when the system is not on? Should there be any lights showing on tje switch if it is in the 'off' position? Does the leds on the controller only come on if the harness is connected to the injector harness on the vehicle?
