Absolutely pull apart the bulkhead connector and check/ repair it, and seriously consider doing the ammeter bypass. Member "crackedback" I believe sells a nice bypass cable.
If you don't have, go to MyMopar and download a service manual for free as well as the aftermarket wiring diagrams on the same site, the go read the MAD electrical article:

BEFORE YOU RECONNECT everything, turn everything in the car off, and insure EVERYTHING is inactive, including the dome lights, etc. Connect the ground cable to the battery LAST with a large wattage bulb in series with the battery ground. If there is a short, the lamp will light, instead of burning down something else
