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)
Wire Strippers AND Wire Cutters (For cutting hard to reach wireties)
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. How To Install Replace Remove a Door Panel Chevy Silverado GMC Sierra 03-06 1AAuto.com - YouTube
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.

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
