There are a ton of good products out there, but I mainly use:
Wash - Meguiars Ultimate Wash & Wax
LSP - Wolfgang Füzion
Spray Wax - Meguiars Synthetic X-press
Sealant Wolfgang DGPS 3.0
I picked up a one owner, mint condition 2008 Ford Edge in Vapor Silver a couple of weeks ago. I was going to get a new 2011, but was offered a deal I couldn’t pass up on my 2008. No regrets at all, I love it!

I wasn't sure what you had paid, but that is usually the problem. I still say you should try out V-LED's. I did a full LED conversion using V-LED's on a previous vehicle and had no issues for the 3 years I had them. I just converted my Edge to LED as well. For example, these are the bulbs I chose for the front parking/signal: http://www.v-leds.com/Exterior-LED/Parking-Light-LED/Amber-LED/V-LEDS-AMBER-92-M-SMT-p7470676-1-2.html
Instead of going through the SJB couldn't you just run your lead directly to the switch with a regular relay in between? I know it wouldn't be the factory set-up, but it would be easier to accomplish and give the same results.
