I'm wiring my custom W/M injection system and need to know what VEC-II output is the 12v- PWM lead. The VEC instructions do not indicate what Master or Slave output is the PWM one. The Settings page on the software lead me to believe pin #5 has to do something with PWM, but that info does me no good in and of itself. Also, I "assume" that the 12v- function is a grounding function the VEC performs when used as a on/off signal and that whatever Master/Slave output this turns out to be, it would go to the Ground pin on the relay with a 12v+ to the "switch" pin on the relay.
Help appreciated. I've asked Sean but its Saturday AM and he's probably taking some well earned time off.

Pin # 5 it is..off the Slave....right to the ground of the relay. Works like a champ! Thanks Bob D and Sean for their prompt replies. A DYI water/methanol system is realy easy to create should anyone think about doing one. Now off to tune.
