OEM Hitch Wiring Adapter
So I am looking for an adapter for the OEM wiring to connect trailer lights. I bought a 7blade to 4 pin adapter, but it doesn't seem to want to be inserted. I have literally never connected one before.
To my untrained eye, the male pins are too wide to fit into this socket.
I went to a farm and fleet who had a variety of trailer wiring accessories, and I didn't see anything that would fit.
I tried using AI to see if the OEM was anything weird and it kept saying it was a standard 7 pin blade RV connection. I browse Amazon and again, didn't see anything different that what I already have.
Am I just not being forceful enough has anyone successfully connected trailer lighting to a new 2026 harness?
Any help would be appreciated.
