Question Umbilical and 7 Pin adaptor issues

When I picked up my "new to me" AS the PO had wired the pigtail with the newer "common" plug (7 pin plug with the flat connectors in the round Plug). What he didn't know was that the "old" 7 pin plug with the round connectors isn't wired the same as the "new plug". So when I plugged the AS into my Pick-up funny things happened. With the truck turned off I plugged the AS into the truck. As soon as I did that the truck running lights came on, as well as the back up lights. I rewired the plug to what I think is the right format, but can't get all of the componets to work. I currently have only turn signals, brake lights, and back-up lights. I don't have running lights, running tail lights, electric brakes, or the acc. power. I have looked at the trailer service guide and it shows that after the wires come off the pigtial they have a fuse (box???) in them. 15 amp I think. I cannot locate these fuses (box???). Any help would be greatly appreciated, I'm started to get frustrated and don't want to have to spend the $$$ to take it to the garage to find the problem. Goodness knows that I need the $$$ for all the other repairs that the trailer needs.

Thanks,
Lowell
