You shouldn't have to take the gauge out. Pop the seat out to give yourself more room to work. I put a plank down to lie on while under the dash. Disconnect the hot wire from the gauge and install the runtz. The hot wire attaches to the other end of the runtz. The black wire that comes out of the runtz connects to ground - probably can connect it to one of the screws that holds the cluster to the dash.
