Methanol question

Methanol question I just finished up my meth installation. It is an Aquamist HFS-5 kit. It's one of the older kits,but I got it used at an excellent price considering what it used to go for when it was new. I will be setting it to engage when my injector duty cycle reaches 60%. However, it needs to read off of negative pulses. Here is the instruction from the installation PDF:
12. System trigger signal input
Choice of two system
triggering signal inputs.
Selectable by jumper
links (page13.18)
PWM IN (pin17):
It reads and translates any
negative going pulses such as fuel injector or
PWM based pump speed co
ntroller in to a refer-
ence signal to trigger the system and fail-safe
circuitry.
The system is factory se
t to detect negative
PWM signals. Some pump
speed controller uses
a positive PWM switching driver, you need to
re-configure the DDS3 circuit board manually,
(p15.F).
That was a copy, paste so sorry for the difficult read. My question is, which color wire from my injector do I need to tap into to get this to activate the pump? This is the last step in my install and need a little help here.
Thanks-
