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.

I am in the same boat you are in. Just purchased a 2004 2720SL and am driving from Florida to Maryland this weekend. I took Bill's advise and had a Tekonsha Prodigy installed on my wife's 2007 Toyota FJ Cruiser beforehand. I am lucky in that a fellow coworker owns a 2720 so I was able to hook up to it and test it out and set the boost. Thing works great. Id suggest spending the money. You can get a cheaper controller if you like but I like the prodigy. Spent 330.00 installed. Was well worth it so far.
