I used the American Autowire Highway 22 kit. It's hard to beat this product. Each module (ignition, gauges, steering wheel turnsigs, horn, etc.) comes with about 6/10 feet longer wire than you need. You could mount your fuse panel all the way back in the bed if you wanted to. The advantage of the longer wire is to allow you to tuck your wires back and hide them. You can easily add courtesy lights under the dash and elsewhere, turn signals, additional gauges; it allows for 22 different panel connects. The directions were very easy to follow.
