I got one... Install is pretyy easy.. All it has is 12v hot and ground, and then one wire that goes into your o2 sensor. There are three wires coming out of your sensor, They are a hot, a ground, and the third is the sending wire. The sending wire is what you have to tap into. My gauge cost me around 40-50 bucks.. Works good and looks good too. If you need a pod piller check out www.lo-tek.com They make a pretty nice piller. It replaces the whole piller instead of just being a little cover.
