This is a Primus trailer brake controller. I had it on my Dodge 2500 for 2 years and it was flawless. I have the original Universal Wiring Harness for it (unused) as well as the vehicle specific 3020P for the 1995-2008 Full Size Ram. Paid over $100 for it and another $15 for the Dodge Harness.
$50 for the whole shebang.
Email me. If you PM me here I may not get it for a few days. thebrickboy@gmail.com
[quote]A totally proportional electric trailer brake control. Primus utilizes the primary sensor technology from Prodigy and features a one step "Point and Go" set-up system. Easy-to-set system allows the driver maximum flexibility when determining how the trailer should respond to a braking event. Snap-in dash mounting clip and removable electrical connector allows until to be quickly stored when not in use. You will appreciate the digital readout depicting a secure electrical connection and the amount of voltage delivery to the trailer brakes. Meets National Highway Traffic Safety Administration (NHTSA) regulations regarding tow vehicle/trailer light activation.[/quote]
