autometer quick shit light on a fields vtec controller
 

I am trying to hook up an autometer quick shift light to my fields vtec controller. So that instead of the buzzer coming on I will get the shift light. I took out the circut board from the fields but don't know where to tap. Does anyone know where i can get the wiring diagram for the fields vtec controller (boxer series)? Or know where on the board i can tap.
