IMO, it's the NSA READYBRUTE/ELITE with the optional READYSTOP breakaway feature for simplicity and the best bang for the buck.
A variety of base plate brands can be used and NSA will supply the adapters. I chose a DEMCO for our Wrangler.
Wiring can be done in a number of ways and in the case of the Wrangler, I chose a COOLTECH wiring harness.
