This is the original OEM control box used on most Paladin, FFC and Bradco attachments.  It has an 8 Pin Deutsch plug on the end so that you can control up to 4 functions on a Cat/Terex/ASV attachment.  One end connects to your battery and the other plugs into your harness on your attachment.  The box goes inside the cab and allows you to control your attachments solenoids directly.  Purchased from the dealers, this box is expensive.  Purchased from us, it is a steal because we remove them from equipment and replace them with our controllers.  Get them while they last.
