Jbatliner, Wiskytango. Maybe this will help. I just put the new 2015+ tow mirrors on my 2013. At first I used the diodes and 350 resisters to feed the amber lights so they functioned as marker mights as well. When I put the power to them nothing happened. With the parking lights on I hit the blinker and the amber lights blinked bright to dim but wouldn't stay dim when I turned off the blinker. Long story short, after drinking a few more Colorado koolaids I said F it and and I spliced in a ground wire from the amber light ground and ran into the door and grounded it to one of the studs that bolt the mirror to the truck. I turned the parking lights back on and that was the problem, I had to ground the ambers to make them dual function. They work perfect now.

 

Thank you Turbo_Drive. Sounds like I will be opening up my mirrors again this weekend to get a reliable ground source. I am thinking that I will put a tester on the other grounds in the harness (Possibly the one for the heat function as it is right there.) and hopefully use an existing wire. If that does not work I will run a new ground. Thanks again!

 

No problem bud, good luck

 

Hey Turbo_Drive, by splicing into the "amber light ground" are you talking about the turn signal ground wire that the front amber light shares with?

 

Bump

Do any of you make/sell the 4: 3 amp 200 piv diodes and 2: 68 ohm resistors all assembled as how bsul92 shows in his Youtube video. Ive never been great with this sort of stuff, installing these if they are already properly assembled will be easy for me, but when it comes to ohms/diodes id rather have someone more experienced than me handle this.

If you do, message me please, would like to install this on my 05

 

This was easy as all heck to do, love the look now

 

Subbed for later. But I think my eBay mirrors have different wiring? Has anyone run into the same problem?

 

Great write up/video. Need to find a set of tow mirrors first.

 

Tried to pull apart my ebay cheapiest, ended up breaking a mirror.... :frown2: So i ordered some Boostautoparts prewired dual function mirrors, priced reasonable and quick shipping. Thinking next week ill get to mounting them up.

 

the wire you showed in your video on my ebay mirrors is grey. mine also have the mirror side signal. If I do this are my mirror arrow lights going to come on as markers as well?

 

In this tutorial, you will learn how to make the signal leds in your mirrors dual function as running lights and blinkers. This will work on any 03-06 mirror with a signal. It is geared towards aftermarket tow mirrors with the amber Leds on the side. It will work n mirrors with red arrows, however i advise against that.

This tutorial is for 2003-2006. If enough people want, i will do one on 2007-2013 as it is a different procedure. What you're going to need:

4: 3 amp 200 piv diodes (radioshack)
2: 68 ohm resistors (radioshack)
Screwdriver
Solder/Solder Iron
Wire Strippers AND Wire Cutters (For cutting hard to reach wireties)
Electrical Tape
Wire Ties
Socket Wrench with 6" Extension
9/32 Bit & Torx T20 (For removing Door panel)
10MM Socket (For Removing Mirror)
15' Wire (16 Gauge is fine)

Ok first thing youll need to do is remove the door panel. 1AAuto Made a great video of that if you dont know how.

On your mirror hatness, there should be two plugs, One black and one blue. We will need to tap into the Blue/White wire in the Blue plug.

Step 1: Solder a diode in line on the blue wire.

Step 2: Solder a diode in so it goes the same way as the other diode, but meets the blue/white wire after the first diode. (I know this is hard to explain, see wiring diagram for details)

Step 3: Solder a 68 ohm 1/2 watt resistor in on the front side of the diode in step 2.

Step 4: Tap into the front left parking light wire, run a wire into the cab and into both doors. It will connect to the 68 ohm resistor.


Wiring Tap Diagram:

Here is a detailed video showing where i tapped and where i ran wires.

It is really simple to do, and it looks great on the truck. Mine have been on for about a week, and 5 people have stopped me and ask how i did it. So im sure this will be of use to some people. Heyyaa

Did you do a writeup for 2007-2013 models?

 

Does anyone have I'll instructions for on how to wire a 2008 Duramax Diesel?

 

This is fantastic!
I love the idea of wiring in the diode at the plug in at window switch, instead of prying off the mirror glass and stuffing it in there.
I have a snag though.
I am putting 2015+ mirrors on my 2006.
What color wire do I add in the diodes? I don't have a blue with white tracer wire in the blue plug in. If nobody knows what color wire to use, how about which pin position I should use?
For those of you who pulled the running light signal off of the window switch, which wire did you tap into? I don't want to run a wire all the way to the fuse block under the hood to find a running light. I probed all the fuses on the left of the dash inside the cab, and none of them come on just with the running lights.

 

anyone? Going to start this project tonight.

 

I’m actually going to do this project this weekend, I’ll post my findings. Unless you’ve figured it out then save me the trouble an let me know lol
