FTDRL Install for a Chevy Avalanche

Ok, I have been getting a lot of questions about this mod and I know the directions are out there, but I wanted to make a very clear step-by-step set of instructions for the electrically challenged people (like me!). Not to mention 2002 directions get mixed in on some older threads and it gets confusing.
Here are the directions for the diode method for 2003-2006 Avalanches to get:
• FTDRL’s (Full-Time Daytime Running Lights) and
• All-On-High (High/Lows/Fogs/DRL come on when switching to high beams or using "flash to pass")

Materials
• 4 Diodes (I used N914-Type Diodes) Pic 1
• Heat shrink (optional, but highly recommended!) Pic 2
• Knife or scissors to cut heat shrink tubing
• Lighter or heat gun to use on heat shrink
• Pliers to remove relays (sometimes they can be difficult to remove by hand)
You can find both the diodes and heat shrink at your local radio shack. My diodes came in a 50 pack (only about $2) and the heat shrink came in a variety pack with multiple sizes (also about $2). I used the smallest size shrink wrap from the pack)

Directions
1) First we will need to prepare our diodes for installation.
All you need to do is wrap them in heat shrink. So take some of your heat shrink and line it up with a diode like I did in the previous picture (yours will be longer as I had already cut mine in that pic). Cut the heat shrink with a knife or scissors so that just a bit of the tips are sticking out when the diode is inserted into the tube of heat shrink.
2) Now before you heat shrink it look at the diode.
Note the black stripe on the center piece of the diode. Remember which side this is on before you heat shrink. Center the diode in the heat shrink tube and hold a lighter up to it. The heat shrink now forms tightly around the diode! (see Pic 3) Do this with 4 diodes (making a note of which side the black stripe is on for all of them). You might want to mark the tube with some white out so you don't forget. Another option was provided by BaritoneAV
