We have a 2011 pj Trailer with electric over hydraulic braking system. The Problem is the brakes are not coming on. Everything is good up to the trailer and thats where my wiring is wrong somewhere. If anyone has this system, can you post some pictures of the wiring block thats located on the inner goose neck rail. Im trying to figure where the correct placement is for each wire on each one of the studded post. PJ's wiring diagram doesn't show me the pump wiring in the schematic. thanks for any help
 
Before you beat yourself up, does your trailer plug on the truck have the 12V constant power connection active on it? That's the connection for charging RV batteries, etc.... That wire is required to power the actual pump unit on 99% of those E/H brake units.... Had a trailer I rewired that wouldn't work on the guy's truck.. Worked on mine, and mine worked on his.... Finally figured out his trailer charge circuit on the truck had a blown fuse..... Replaced it and all was good.
