Wire colors:
White/Orange = 12V+ Switched Ignition Power
White/Blue = Ground
White = Flex Fuel Signal (this harness already includes the necessary pull-up resistor for use with DS1)
Pin 15 in the OBD2 connector will need to be removed and covered with the supplied heat shrink, tape it up to the harness and out of the way. Insert the new Flex Fuel Signal wire into pin 15 after crimping the pin onto it.
12V+ Switched Ignition Power can be obtained from the Fuel Pump fuse
Ground must be installed on a secure and clean bare metal ground point.
