Trailer plug and electrical craziness

I finished hooking up the new trailer plug (combination 7-pin and 4-pin), along with the plug in the bed too. I bought a little butane torch and for the first time ever, managed to do a fairly good job of soldering wires (sometimes as many as five) together.

I wish I could test the work, but the electrical issues in the Ram have just gotten worse. The dashboard is going crazy and now has started displaying “no bus” with the key on/engine off. I need to check several more things, such as: the radio connections; corrosion under the fuse box; and the ground strap at the bellhousing. Cleaning the connectors on the back of the instrument cluster had no effect, nor did cleaning up all the battery posts, all the ground connectors in the engine compartment, and the main fuse box power lead.
