I have a recently purchased (used) 2013 Thor ACE 29.1. There are two 12V cig/power outlets on the dash, with wires attached, but it appears to me that they have never been connected to power. There is a fuse F17 "Power Point" in the RV Custom Products BCC (Battery Control Center) box in the engine compartment. The fuse is OK, and should be the one for those outlets. But it's associated with the P4 accessory connector, which does not have any mating connector or wiring harness. I suspect that this would only be provided if the original owner had ordered a higher-level accessories package, which this coach does not have. So apparently it's possible that even though some items may be there, they were not necessarily ever wired or made to work, depending on the accessories package that the coach was ordered with.
