I am installing 2 Fantastic Fans in the ceiling openings.
I found the brown and white 12V wires doubled-back and zip tied to the rest of the wires in the wire channel in top cabinets.
I was wondering how to get the wires to the ceiling opening without disassembling the interior.
Is there an OEM hole in the aluminum frame member where the upper cabinet screws to the ceiling?
HELP!!
Thanks.

Yes but I can't find any holes through the aluminum framing through which I can pull the wires.
Are there any holes that GMC put in for these wires maybe hiding in the foam?

Its been my experience there is plenty of gap between the ceiling and the foam to fish about anything thru. I claw hammered my ceiling out so maybe I'm wrong. But I remember a good amount of gap.

The cabinet when screwed to the ceiling pulls the ceiling panel tight against the aluminum so there is no room for a wire.
There must be some holes through the aluminum somewhere close to the vent hole but with the ceiling panel in place there is not much room to see where a hole might be.
So I am hoping someone else has had to put this wire in place and can give me a clue where the holes are.
I am thinking there may be spray insulation obscuring it.
Thanks,

You need to lower the area around the opening and also cut a notch in the
cabinet area and shove a electricians wire chaser to the opening, then pull
new wires to the edge.

Yes. There are holes in the overhead structure for wires. I continue to have no luck understanding the photo site but go to this location and you should see 3 pix of how my '73 is configured.
http://www.gmcmhphotos.com/photos/interior/p49464-fabricating-ac-ducts-insulating-ceiling.html
Under the 3" plastic cover above the windows is a wire "chase". A notch has been cut to allow wires to run up to the center of the ceiling. Mine has 2 pair, one for a light, the other for a fan. Adjacent to the fan opening are holes through the roof structure into the fan opening. My coach was pre-wired up to the hole, it was necessary to drop the ceiling to find the end and feed it through the hole.
If yours is not pre-wired, you may be able to get a snake from the wire chase up to the fan opening but getting it through the hole will be a challenge with the ceiling in place.

I got it almost done today. It was a royal pain!!
For both the front and the rear this is what I had to do:
There is a channel roof rib in which the wire is supposed to run and it was full of foam.I tried to run a fish tape but there was too much foam. So I cut a 2-1/2 wide slot in the ceiling board inside the cabinet, cut out some foam and then I could get the fish tape started from the cabinet thru the channel to close to the vent opening. The channel is 6 inches to the rear of the vent opening. There were holes thru the ribs between the vent opening and the channel. I was able to fish the wire up thru the channel and then turn it 90 degrees and fish it thru the holes to the vent opening. All thru a 1" gap created by gently pry down the ceiling panel around the vent opening.
The wire for the rear power vent was also doubled back and zip tied to the harness inside the long channel inside the upper cabinet. The trouble with the rear wire was it was zip tied behind the closet!!!! I had to take out the ceiling panel between the closet and the bath modules, loosen the attachment brackets that hold the closet to the ceiling, pull the top of the closet out about 1/2 so I could get my hands up to the wire channel from inside the closet from below the closet shelf. I felt the zip tie and cut it without cutting the wire too!! woohoo! Then I undertook the same fishing expedition for the rear vent.
While I was at it, I also loosened the screws that hold the closet module to the floor and put a jack between the kickplate and shoved the closet bottom and rescrewed it down. Now my bathroom door no longer hits the bottom drawers when it is opened all the way!!
Tomorrow I will finish screwing down the units, seal around them and install the trim piece and I am done!!
Thanks to those who tried to help and to whoever it was that posted the GMC_Assembly_Manual.pdf. It showed where they intended to run these wires. I just can't believe the wires were not in place up to the vent opening before they sprayed the insulation all over. Gouging out insulation with a fish tape is no fun...
