JEM-Sport – EcoBoost Swap Wiring Harness – Chassis/Patch – 2018+ EcoBoost Mustang

JEM-Sport – EcoBoost Swap Wiring Harness – Chassis/Patch – 2018+ EcoBoost Mustang

The JEM-Sport patch wiring harness and fuse box kit for the 2018-2023 2.3L EcoBoost Mustang handles everything on the chassis side of your engine swap — including full 10R80 10-speed automatic transmission support. No additional controller or module needed. Paddle shifter inputs are included as well. Manual transmissions are supported too.

This kit serves as a direct replacement for the discontinued Ford Control Pack patch wiring harness (M-6017-20T, M-6017-23T, M-6017-23TA) and is compatible with crate engines M-6007-23T and M-6007-23TA. Designed around the 2018-2023 Mustang PCM/ECU and engine wiring harness — if you pick up a used lift-out EcoBoost with the engine harness and ECU intact, this is the only additional wiring kit you need to complete the swap.

All wire, pins, and connectors are new. Everything terminates to the 2nd main ECU connector.

What This Kit Covers:

• Power distribution
• Fuse box
• OBD2 port
• Accelerator pedal
• Clutch and/or brake switch
• Ignition switch
• Start switch
• Automatic transmission
• Paddle shift inputs

Confirmed Compatible:

• 2018-2023 Mustang 2.3L EcoBoost — 10R80 automatic transmission
• 2018-2023 Mustang 2.3L EcoBoost — manual transmission

This harness will likely work with many other Gen 1 4-cylinder EcoBoost ECUs across Ford and Lincoln models from 2016-2024, though compatibility outside of the confirmed list above has not been tested.

What’s Included:

• Patch wiring harness
• Fuse box
• All new wire, pins, and connectors
