Hi Forum members, On my 2008 e350 is all the wiring there to do a 7 pin trailer connection with brake controller?Is there a manual I can buy to show this.
Thanks Bob

 

I know on my 1999 E350 it has a harness that has all the wires for a 7 pin but you have to get a pigtail that plugs into the connector or splice into the wires. Should be a bundle of wires behind the axle on the driver side. The trailer brake harness is near the kick panel on the driver side also.

 

Thanks you
