Tow mirrors.

Angelef9 · September 20, 2015

Hey guys im new to the forum.. Just got my 2015 Sierra and was wondering if the 2500 tow mirrors fit and if its a plug and play with everything working like power folding and signals..

TIA...

It is not 100% plug and play the mirrors will powerfold, adjust, and turn signals will work but the front ambers and back up lights will not.

Ok thanks and what is needed for the rest to work??

Here is the thread that helped me with this. I ended up doing exactly what Mike1220 did. And below is the post he made that i used. There are also a lot of other ways people have done it that are mentioned in the thread.

Hey all, just wanted to add this info to the thread incase anyone is looking for a very simple way to wire in these mirrors so that the white lights activate with the cargos and the ambers act as turn signals (as far as I know theres no way to make them into running lights without having to run a wire to the ambers)
Also, I can only guarantee that this will work by this method with a 14' 1500 Sierra (should be the same with a 14' 1500 Silverado). I am not sure on 15'+ 1500 or 2500s. I can't imagine that it would be much different though if at all.

ALL MODIFICATIONS ARE MADE ON THE MIRROR HARNESS, the door harness is left untouched.

So all you will need for this is some wire cutters, 2 quick wire splices, and a diode

You will want to cut the orange wire on the mirror's harness a few inches away from the plug (the farther the better but I don't think you need anymore than 5-6" coming from the plug to keep this easy)

So after you cut the orange wire you will splice it into the Red/Blue wire which is for your turn signals on the mirror side. So now you have the ambers working as turn signals

Next to get the white lights to work as puddle lights you will be able to just splice the yellow wire to the orange wire that is now coming out of the mirror harness plug since that is connected to the puddle lights.

BUT WAIT, you're probably wondering why I originally said that they will work with the cargo lights, not the puddle lights. Well heres where the diode comes into place.
Inspired by the "Cargo lights on with reverse" and "Fogs on with high beams" mods, I decided it'd be worth a shot to make the puddle lights turn on with the cargos.

In the end, your mirror harness will look something like this

This is from Morrislee who made his cargo lights turn on with the puddle lights. SO in order to make the puddle lights work the cargo lights, you will have to put the diode in the opposite way from how it is pictured. SO the stripe will be on the same side as the grey plug and not the pink.

I decided that using this picture would be more beneficial to everyone since it is much cleaner. I have 3 diodes in this area so since there is only one in this picture, it is much easier to see what needs to be done.

EDIT:
For those of you on tapatalk I am just now realizing that Morris's picture is not coming up. So here's a link to the post: http://www.gm-trucks...ghts/?p=1533886 (Post #64 in the "cargo lights on with reverse lights" thread)

And here's the pictures he posted: (like I said earlier, the diode will need to be reversed. I just want to make sure that anyone who does this remembers to reverse the diode because without doing that, it won't work properly)
