The instructions say to run the white wire from the NMU to the output voltage lead from the throttle position sensor. Where is this? Pics would help. And to mount the switch it says to run the red wire to one of the switches leads and the other lead needs to be connected to a 12-volt accessory source under the dash, using a t-tap electrical connector. What do I use at the 12 volt accessory source? Where is it? And what is the T-tap electrical connector? Again pics would help a lot.
