Aquamist 3 issues

[Nicknacke36]

Hey folks! This is my first time on a forum so be nice 😁

I have recently fitted an aquamist 3 kit on to my naturally aspirated BMW 323i E36. - I have the intention to turbo the car, hence fitting the kit.

My issues are as follows:

I have a green IDC light in the control unit, however no light on the gauge.

When the car is revved the relay clicks constantly whilst water injection is engaged and the "B" light flickers with it too.

I have no red bars showing on my gauge whatsoever. - I have tested the gauge by moving the pin in the controller and it worked fine then.

When the water does inject, the water level light comes on momentarily after even though there is adequate water in the tank.

One note to mention is that when I bought the kit, annoyingly the cables (fav, water sensor, and tank water level) had been cut. All of which are correctly reconnected in accordance with the wiring diagram included with the kit. Perhaps the resistance of the cables could upset it?

I am eager to get the kit working so any advice or pointers would be super helpful! 😊
