The new Gate-Way for the 1999-2004 Mustang GT & Cobra is your connection to all the great feature and tuneability of the Holley EFI ECUs without losing the major functions of the factory dash and accessories of the Mustang GT& Cobra.
The Gate-Way plugs right into the OEM connectors that is located in your passenger kick panel that originally plugged into the factory ECU. Then the Gate-Way harness runs under the carpet and mounts the Holley EFI under your seat. No need to do any custom wiring. 

Hook up your power leads, wide band sensor and MAP sensor. Then you are ready to go.

The included wiring harness uses a CAN connector to accept handhled tuning monitors or the USB to CAN cable for laptop tuning (*optional cable select above)

Once you have installed the Gate-Way/ Holley EFI and have it setup on your car. You can switch to the Gate-Way/ Holley EFI from factory ECU at the track in about 15 minutes.
