I'm trying to get this system all up to spec, but have run into a few issues. First, I have the replacement 90 degree joints for the headlight sprayers, but I can't figure out how to get the tubing off the old ones. Do I need to remove the entire headlight assembly (I took off the turn signal and outer bracket) or is there an easier way to do this? Second, where is the motor for the rear window sprayer? When I press the switch (this is supposed to spray no?) I don't hear the noise of an electric motor anywhere, is this run off the same reservoir as the headlights or the windshield. Thanks - still need to get that FSM
