Its a standard loom which is way loner all round than you would need so you just trim back to suite. Basically decide where you want to bolt the fuse box and then run wires from there. One big advantage is that every wire has its use printed on it about every 12" so its very easy to figure out what needs to go where. I fitted mine and had most circuits up and running in a couple of days. Being of American production its all very simple and a bit over engineered but I when you compare that to the nightmare of dealing with an old loom for me it was a no brainer. They do several types just pic the one with enough circuits for what you need.
