Fleetwood Angler wiring

[BillWAZ]

I searched all the old stuff, didn’t find anything related,  I did find a copy of the brochure that helped in some areas,  However, I am now looking for some wiring answers.  The Angler seems to have been somewhat bareboned.  Only 2 overhead lights, 3 AC outlets.  It did have outlets for electric jacks,  good, but have manual (for now).

It has speakers mounted and wiring into the cabinet by where a radio would be mounted.   I want to wire in an exhaust fan over the bed, and trying to find a good 12v source.  Repurposing the wires to the speaker over the bed sounded to me like a good option, but does not seem to be continuity from speaker to the wires, plus the wires are a different color.  

Hoping a fellow Angler owner here might have what I am looking for.  

Mine is  2002 9D with extenede cab over.

Thanks for the update. Glad you got it figured out.

UPDATE. DONE.  
OK, so the wires I found labeled as speaker wires were not speaker wires.  Oner pair went to the power center, the other pair went to radio enclosure.  Up thru small hole in ceiling and a 90 degree bend to a roof strut, tugging on either end to no avail, so considering I won’t be using the speakers, I just tied into these 2 wires and got power out the other end.  Easy matter of routing thru to the roof vent.  Now I have an exhaust fan over the cab over bed.  Project almost done, should finish today, but the difficult section finished.

Can you pull down the speaker and tie a string to the two wires just in case. Then go over by the stereo hole and gently pull on the individual wires and see if you can identify the two that go to the speaker? Hopefully the wires are not stapled in the ceiling. The string is in case you accidentally pull the wires up into the hole.
