two legs through the drivers side firewall hole that you cut
in step two followed by the shorter leg though the
passenger side firewall hole. Continue pulling the harness
legs through the firewall until the rubber grommets seat

properly seated into the firewall, each leg can be routed
between the manifold and the valve covers.
The drivers side leg will contain connectors for the following:
• MAP (3-pin green male connector)
• Computer Controlled Ignition (4-pin male black
connector, for a TFI you will use the TFI adapter)
• ESC (purple wire, bare lead)
• Air (2-pin gray connector)
• Coolant (2-pin black connector)
• TPS (3-pin black male connector)
Make sure to connect the switched +12 volt wire (long pink
wire with a female spade connector) to a switched ignition

vehicle will not start.
NOTE: If you are not controlling timing with the ACCEL
DFI ECM (using a non-computer-controlled ignition system

connector) or the ESC connector (purple wire with bare lead).
The passenger side harness leg will contain the following
