Troubleshooting Hyperflash Blinker 2025 Ford Maverick After Trailer Wiring Install

Updated 04/25/2025 | Published 04/18/2025

Question:

I have this wired on my 2025 Maverick, but it makes my dash blinker go really fast, even though the lights are all working. Is there a fix for that?

Hey Dalton, the trailer wiring harness installs are not known to cause hyperflashing unless maybe something was installed wrong. Does the trailer wiring actually function too? I would check to make sure you have the fuse installed in the harness and maybe disconnect and reconnect the connectors of the harness as that might clear out any issues with the harness.

My truck is a hybrid, and the wiring kit makes the top lights on both brake lights not work. Is it because of it being a hybrid?

@DaltonB The kit you have now was designed to work with hybrid models so that's not the problem. The fact some lights aren't working on the vehicle currently indicates to me the connectors of the kit are not seated fully. I would try disconnecting them and firmly reconnecting them to make sure all of the pins seat properly.
