Just about to do this on my 06 SD with upfitter switches.
I cant get the OP pics to enlarge any bigger. What Id like to know is how do I plug into the fuse panel.
Running a wire from #3 Aux switch to #39 fuse. Do I just remove fuse & install a U shape wire connector. So both sides are tied into the mini fuse spot or do I cut 1 lug off the connector & go to 1 side of the fuse holder??
I hate wiring & don't want to burn up a fuse panel!!
Update: 2006 uses a Green wire w/violet stripe also, connector is not labeled but it is almost directly behind the mirror heat fuse. This connector is at the bottom of the fuse block, just about in the middle(looking directly at it). It has a looped light blue wire w/pink stripe (gos in loops and gos back in) and the release is on the end of the connector. This should help you identify it. I decided to go with the Aux 2 switch since the factory fuse is 15amps, now I just have to go get a large 15 amp fuse for the switch fuse in the block so the mirror wiring doesn't burn up for some reason. Based on the wire size I think I could've used Aux 3 but why take the chance if I'm not useing Aux 2 for anything else. I recommend a SMALL jewelers flathead screwdriver to pry out the red lock in the center of the connector and then to push in the back of the connector to get it to release the wire, it's no prob if you use that. Hope this helps.
I just wanted to let everyone know that this post is correct for the 2006. I found the wire for fuse #39 (green w/violet stripe), then to verify it was the correct connector, I looked for the blue wire w/pink stripe. The connector did indeed have the needed green w/violet striped wire as well as two blue w/pink stripe wires (I assume the OP was correct in stating it looped back in.)
To verify operation, I turned the truck on and let the mirrors get warm and then shut the truck off. I cut the green w/violet stripe wire and waited about 5 minutes. Started the truck up and after a couple minutes it was obvious the mirrors weren't heating up. Success! I attached a piece of 16 ga wire (all I had, probably don't need it to be that large) to both ends of the cut wire and ran them above the fuse box to the dash where I installed a 15 amp 3 pole lighted switch. I ran a ground to the right side of the dash. Now my switch lights up when the heat is on!
