Does anyone have a good wiring diagram for the turn signal indicators under the dash and tucked up by the steering column? I'm trying to wire new mirrors with heat and blinkers and am looking to tap off of those wires. Any recommendations from anyone on where to pull power for the heated mirrors? I'm am going to run them on a switch as Ford leaves them running whenever the ignition is on.

Its not like heated mirrors draw a lot of current.

my 00 excursion has factory heated mirrors, and as far as i know ex's/sd's shared the same harnesses from the front seats forward at least. so, there's probably at least already a dedicated circuit for them (shared with other accessories i imagine), if not even a dedicated wire or blank spot in a harness you could tap into. i can check which fuse mine are on if you'd like.

like optmusprimer said, they demand very little power, so most any 12v supply would be fine. easiest thing to do would probably be to just tap into the 12v constant supply for either the power mirrors or power windows inside the door. hell, that's probably what the factory does if i had to guess.

I thought pretty much anything electrically heated drew a lot of current?

generally speaking, yes. when you're talking about something with a surface as small/thin as a mirror that only needs to hold the temp a few degrees above freezing to be effective, no. they're not designed to thaw slabs of ice/snow within minutes or anything. while they do a decent job of burning through buildups of fog, frost, and even light coats of ice, they still need to be manually cleared of anything thick. they will keep anything from reforming, though, unless it's extremely cold and/or they're really getting assaulted with frozen precipitation. the only time i can remember mine being useless was in single digit temps with a negative windshield (at rest, not even accounting for vehicle speed) and snow at the rate of 1-2" per hour.
