So having backed up the boat with just the standard mirrors, my tailgate camera, and my peek-a-boo hole in the middle of my headache rack - my gutter on the corner of the pole building / shop told me I needed more. Quite convincingly. I just barely nicked it, but sure enough - gutter dent popped out & reattachment repair done - it motivated me to buy tow mirrors, these ones: OPT7 Truck Tow Trailer Mirrors - Pickup Heated Powered DOT 10 Yr Warranty | eBay Not the cheapest (10yr warr if they are still around ) - but 1/2 the $$ of buying Mr T’s. So I saved a 1/2 tank worth of gas in the boat. Installed today: Tundra - tow mirrors front by LINUS posted Jun 4, 2018 at 7:17 PM Wanted a shot to show front shot of truck with mirrors (and a sneaky little boxer butt made the shot). The important facts are the mirrors are 16” collapsed, and 19.5” expanded - measured from underside of mirror. It was pretty straightforward after a quick youtube session to see if there were any hidden ‘gotchas!’ in door panel removal, none found. The interesting part was my Tundra is just a SR5 Rock Warrior, no Platinum, no Limited, just a basic SR5 with some stickers (gone) & a tow package, but aside from a moonroof, no extra options. So I pull the old mirrors & look down the connector - 5 wires. Dang. The new tow mirrors have 7 pins in the socket, so I expect some function the mirrors have won’t work on my SR5. Meh. A beer & a half, some playing with the dog, some improvised tools later - both mirrors in & halfway have them looking right (gaskets sitting right, all that). Cool. Better check ‘em before I button up both door panels. Power mirrors? Check. Defrost? Check. No rattles open/slamming doors with mirrors both extended & retracted. Yahtzee! Ok. Things going good - I’ma gunna push my luck. Turn on the running lights: Tundra tow clearance lights / running lights by LINUS posted Jun 4, 2018 at 7:22 PM Waaaaait - whaaaaaaat? What is this crazy scorcery? OK, so now I’m completely in “how far is this happy bonus going to go?” -mode. So, the million dollar question - do I have turn signals? : Tow mirrors w/ running lights & turn signal (upper row LED’s) by LINUS posted Jun 4, 2018 at 7:26 PM One well-timed pic (took me ~4 tries, but between the beer & the fact it worked, that was nothin!) So for all those who made it to the bottom (or just scanned the pics & wondered how I get through an average day) ——— here’s what you wanted: Cliff Notes - the Tundra body harness that includes the doors has the 7 pins wired in it. Like how the base SR5 has that blank to the right of the cluster you pop out & can add the MFA button bank, or how the LX450 floor harness is a single SKU# for open diffs or e-lockers. I think Mr. T wanted to keep things simple / fewer SKU# to stock, so as I add things over time, I’ll update things like this I find.
