Yes... The problem is I do not have the OEM connector that plugs into the trunk wiring and goes to the trailer connector on the hitch. I can add pins and wire the brake controller up to existing side of the connector, but I can't get a hold of the other side connector that plugs into it. And I can't just crimp a pin on some wires and stick the into the connector without the plastic body.

This is the part that I don't know how to find: https://www.ecstuning.com/Search/X5_Harness/ES185391/

I could assemble it if I could find the individual connector that plugs into the other side in the trunk.

Thank you for your help!
