    I just hard wired truck side (no module). I drained fluids and purged the system, cleaned filters and recharged. Plow angles and lifts strong and fast but it doesnt drop. I didnt know which solenoid controls dump/down so I pulled the top two on the block and the plungers seemed to move appropriately. I couldnt check the bottom one (third) because I didnt have a deep enough socket with me.

    Please advise, any hints or advice would be great, and WHICH DAMN SOLENOID CONTROLS DUMP/DOWN?
