Without further investigation, sounds like you may possibly have a bad/ weak ground or grounds somewhere. When you connect to the toad, the lights work, if I read this right. That might mean the ground in your 7 pin is making the ground connection good and your lights start working properly. Since the lights work, I wouldn't have expected a blown fuse anywhere. Try connecting a jumper wire to the ground wire coming from the problem lights and ground the jumper to the frame. (Make sure you have a good ground on frame) See if that cures the problem, Hope this helps. Good luck.
