    I have an economizer (curtis) sander that has the 7 pin trailer wiring connection in the bed of the truck. I have the controls for in cab and have no clue how to wire them in. The truck has a drawtite brake controller that has a direct plug into the truck. To wire the controller should i splice into the brake controller lines and use that for the sander control? I have a blue, red, white and black wire off the brake controller. The sander schematic calls for a brown, red, black blue and green wires. Any help would be appreciated.
