My new (to me) Viking PUP trailer has a 7-pin "round" electrical connection including electric brakes. My vehichle just has the standard 4-pin flat rectangle receiver on its hitch. I bought an adapter for it but the trailer lights still won't work. I've double checked both the adapter plugged into my vehicle and the trailer lights both work, but still nothing. Has anyone had a similar issue?
