the connector must be down in the door...youve got to be able to pull
the mirrors off (no matter the type...paddle or extendable/tow) w/out
busting the glass each time.
the 99's were extendable and werent lit w/ led's for parking/turn.
i THINK in 00 or 01 they went to extendable towing mirrors
and in 04 (maybe 03 too) they added the leds for park/turn
in 05 or 06 they reduced the number of LED's for park/turn
i dont know at what point they became HEATED and i DONT know
if the heat is w/in the same plug as the power/adjust and turn signal...
the BOLTS etc that hold the mirror to the door should be the same from
99-07 and even the 08s will mount to an older truck
whens the auction end ? ill pull my door apart tomorrow and find
the plug type and number and report back to you if it helps.
when you get your FORD OEM extendable mirrors plan to spend
another 30 bucks for the
C-BETR add ons
once i installed mine i NEVER took 'em off (like i thought i would)
