I have a original Fast system with external Fast ecu data logger, i am trying to hook up the data logger. I know the arming wire and trigger wire need to be grounded to work. My question is can the trigger wire be hooked up to a momentary switch to ground, or does it need to stay grounded for the entire run for it to log. I called Fast and they could not answer my question, I was told they do not remember on the old system. Thanks in advance Jim.
