Oh I get it now.... You added the connector box for the bunk bed light/fan module.
On my setup this connector is on the side of the dual lamp fixture...
Nice job...
My POPUP came with two of these bunk-end fans and they worked for about an year and both quit almost the same time. I picked a couple of the 10-inch O2-COOL fans from Walmart and they really do a bang up job moving some air around. These are AC/DC models and are very quiet in operations.
