There are 2 10mm nuts holding the cable to the servo and the servo to a metal plate (I found out the hard way that its probably easier to remove the 2 10mm nuts instead of the 3 10mm bolts holding the whole thing to the battery tray). So, all you have to do is take off those nuts, pull the cable a little and pull the pin out (be careful, I almost lost mine on the ground), pull the vacume line off, and then the electric control plug has a little plastic pin in it that I pushed through enough to grab it with a pair of pliers and then you can take the plug off and the servo comes out. I don't have a servo to put in my truck just yet and it runs fine without it. So the vacume there isn't that big a deal, but you can take up the vacume line that goes into the servo.
