Default Aquamist 2D install on A4 1.8 - need some help

I'm trying to figure out right now what signals I need to splice into, to make the kit work.

From the description, it looks like I can splice right into the signal going into one of the injectors. My question is this: don't I have to worry about signal attenuation if I draw the current away from just one injector? Do I need to put a signal amp before the injector to compensate? Also, if I only connect the kit to a single injector, the water injector will pulse only when one FI is active - won't this cause uneven water distribution in the combustion chambers? If so, what can I do to prevent this?

Thanks for any advice in advance

Default Should not be a problem

Injectors have a pretty low resistance, no more than 16 ohms. I'm not sure if Bosch injectors are high 16 ohm or low 2-3 ohm types. I'll go measure one when I get a chance. 10 mils will not load the ECU driver circuit.

I'm planning on doing an Aquamist install myself.

Default The controller merely reads the 'pulse width' requested by the ECU to adjust the WI volume. A sample

from a single injector is all it takes.
