Rather than spend $70 + for the plug and play load equalizer III, I bought the Load Equalizer III with wire taps ($36 shipped on Ebay). It was simple to install. Easy to follow instructions. The plug for the rear turn signal/brake lights is under the left side cover. Just tap into three wires and run the black to ground on battery. slight differences with security system, which I don't have.
