My '10 has one and yours should too. Dick is right about the lights, but I find it useful when opening slides and lowering the rear stabilizers, particularly. Was the seller the original owner? If not, maybe it was gone when he took ownership. If by module, you mean the receiver for it, that will be in the front storage mounted on the wall behind the battery. Good luck, hope you can track it down. You could try Keystone, but I doubt they'll be very helpful.
