Swap Gate-Way for 05'-09' Mustang GT
The Swap Gate-Way module (GWFM-0509) was developed for the 05-09 Mustang GT owner that has replaced their original OEM engine harness with a Holley EFI main harness and are using a Holley EFI ecu. The GWFM-0509 will allow you to retain the factory dash functions and keep the factory AC. No matter which engine you chosen with the Holley EFI main harness.
The Swap Gate-Way module will allow the Holley EFI CAN protocol to talk to the OEM CAN protocol which controls the factory dash, AC & back up lights.
No reason to spend the extra money for an aftermarket dash and then try to figure out how to make the A.C. fuel gauge and back up light work.
All your factory gauges, A.C. and back up light will work with the Gate-Way.
The swap Gate-Way will work with any engine and transmission combination that Holley EFI makes a harness for. The Swap Gate-Way is not for a novice at wiring and should be installed by a competent Holley EFI Dealer with the ability to comprehend 05-09 Mustang GT wiring manuals.
On our website, Are the instructions for the GWFM-0509 (which we recommend that you read prior to purchasing the GWFM-0509).
Theses instruction will also help you wire a Coyote engine with a Holley EFI main harness 558-110 & the transmission harness 558-470. To the factory Ford harness and well as the Gate-Way harness.
Other Holley EFI main harnesses could wire up differently to the Ford OEM harness.
The Swap Gate-Way wiring will wire up the same no matter which Holley EFI engine harness you use.
If you are planning on using a transmission that is not supported by Holley EFI. You will need to figure out how to get a signal from the transmission to the Holley EFI. So Holley EFI will read MPH. The Gate-Way gets it'd input for the MPH from the Holley EFI CAN to make the Dash speedometer work.
