Question:
I am looking for a 7 blade wiring harness for a 2026 ford transit 250 with extended wheel base 148. What wiring harness complete kit would have wiring long enough for this van?

Hey Mark! To add a 7-way to your 2026 Ford Transit T250 you need to start with the Curt T-Connector Vehicle Wiring Harness # C56327. This plugs into the connection points behind your tail lights and will provide you with a 4-way.
From there you can upgrade it to a 7-way using the # ETBC7. This comes with the adapter, wiring, and everything you need for a complete installation. The wiring will be long enough to run the brake output and hot lead in your Transit.
I went ahead and attached an installation video further down on this page for your reference. Are you towing a trailer with brakes? Do you have a brake controller already?
