Ok, after hearing multiple stories how easy the progidy wireless brake controller works I figured out my pins are not powered correctly on the 7 pin. After 3 calls, 2 service appointments and 1 yr they are telling me I need an retrofit kit for my hitch and it was not part of the original sales agreement last April - so I need to pay for it, $630.
Has anyone heard of this? Who buys a hitch that doesn't work correctly?
