I started to do this myself, but at this point in life quickly realized I'm past the point of wanting roll around on the ground in the Texas summer heat and getting the readers out to look for colored wires. I simply called a local independent car audio shop who said "no problem". I went through the instructions with him (you should do this as he thought he was going to have to take the bumper off!) I told the kid what I learned off here (possible short lead to the passenger side if not run right, and relay may not reach to the back of the fuse box for mounting. Also, be careful when hooking wire harness up as it may push pins back). I also copied post #153 from 4doorharley and told the kid I wanted it like this for the courtesy feature to work. Exactly one hour later my car was being pulled back around and everything works perfectly! 100% with no lights on and 70% with. Turn signals and courtesy function. It's a perfect match to the switchbacks I already had in place of the original turn signals (YES, I CAN STILL CHANGE BULBS!). The shop kids all thought it was pretty cool and commented on ease of installation!
Well done Dan! This is exactly what the Edge needed! The only thing to monitor now is durability. They've already been through a thunderstorm and all is good. Can't wait to see what you may or may not be doing for the rear lights!
BTW, total cost for my air conditioned comfort, $75. Well worth it to me!
