Because the SLT model did not have the option of a factory ceiling mounted DVD player, I will now be installing/ or having one installed afterwards. I'm assuming the unit would need both constant 12v power, as well as switched 12v power. Would the truck be already pre-wired for this installation, if not, where would I hook into for the 12v power? Does the ceiling of the truck have a mounting plate factory installed for the mounting of the DVD player?

Looking at installing side mirrors that have the turning signal lights. If I was to install these, would there be a factory harness in the door because this was an option on the SLT model? If not, where would I take the wiring back to?

Also, what accessory store seems to be the best for buying aftermarket accessories Dodge Rams? I'm in Canada, but don't mind from buying "state side"

Thanks for any information you can give me!
