I don't know where it is on your buggy, cause I've got the 4.0 but I cut the leads off so I could use a standard deep socket rather than buying a special one, and then used a box wrench to install the new one. Be very carefull taking out the old one because it's got antiseize on the threads but won't come out easily. It's best to work it back and forth slowly a little at a time until it loosens up. Tighten the new one and snap the connector together. Done.
