I looked up your owner's manual online and the 12V power issue is likely a fuse issue. You will want to check the 30amp fuse number 16. This will be in the power distribution box under the hood.

I recommend using a circuit tester like # PTW2993 to check power on either side of that fuse. If you have power on both sides, then you will want to trace that wire from the fuse box back to the 1 o'clock position on the 7-way. If there is no obvious damage, you will want to check that wire by probing every 5 feet until you find where the power drops off. Then you can replace that wire with # 10-1-1. If you want to bypass that wire and fuse, you can do that by running wire from that pin to the battery using that same # 10-1-1 sold by the foot. You will need to use an in-line circuit breaker like # 9510 to protect the connection.
