The valves are actually fairly easy to install. You can put them in loosely and route the power and ground up through a grommet in the spare tire well. Make the power connections then use the remote to actuate the flapper. With the flappers open, you can align the valve body and tighten the bolts. Lastly, you can program the open and close buttons to your homelink buttons if you like.
