I've got a 99 F250 superduty and would like to upgrade to extendable towing
mirrors but have been unable to find any that suit me.
Currently on ebay there are several different vendors offering powered mirrors
which will fit but I don't know if I can just install the powered mirrors and
not hook up the control wires? I don't know if the mirrors will stay in focus
without power or even whether a person could adjust them by hand.
