I finally got to put a trailer behind the truck after installing my prodigy. No luck.
With trailer connected and prodigy plugged in, it shows the two dots (as if no trailer connection) I have full light function and the trailer brakes are fully on.
I disconnected the trailer wire and the brakes are off. (obvious but they function)
I disconnect the prodigy from the wire and still have locked brakes.
I disconnect the wire from the truck's box and still have locked brakes.
I pull the fuse from under the hood and the brakes unlock.
If I use the manual lever (under any conditions) it shows n.c.
I will pull out the install instructions and read further but I am thinking this is a truck wiring problem. Any thoughts?
