Prospective buyer electric brake question

I purchased my Prodigy brake controller for my 4Runner from www.southwestwheel.com and it came with a direct plug in harness. Very simple installation and has worked well for my purposes. I just double-checked their website and they still offer the direct plugin harness with 2 Day FedEx shipping included for $124.95. What is new is that there is a $20 rebate available. So for $104.95 you could have a "plug and play" brake controller before you leave. Just a thought. There are a couple of pictures of my installation on the forum. Search on "4Runner Prodigy Install" or my user name.
