Easy to install and inexpensive peace of mind. Instructions are a little lacking but if you look at the pictures and look at your Jeep, they make sense. The only thing I didn’t different, that the instructions don’t say, is at the passenger head, I left the OEM 90 degree rubber elbow with the hard plastic line and cut the plastic line about 3” away from the boot. Then I slipped the provided hose over that and clamped it. Made the angle to the back of the head much easier.
