am tring to wire in my water injection and have come to a standstill.
the system i have is the aquamist 2d system using the FIA2 controller. on the wiring diagram it shows a purple wire going to "FI % monitor (0-5v = 0-100%)"
anyone any idea what this is? sounds like a lambda connection but its not clear.
this is link to diagram: http://www.aquamist.co.uk/press/806-...struction.html
will phone aquamist 2morrow but thought i would ask whilst i'm under the bonnet!
