Okay, one last question, when I hook up Ol' Ugly, do I do this with a fuse installed in the that location of the fuse panel or do it without a fuse?

Without... that's the reason for it not to have a fuse to blow.

OK, here goes. To test the circut without wasting numerous fuses, plug in a headlamp bulb where fuse goes. Yes you will have to make an aparatus to adapt the headlamp and wires to where the fuse went. The load that the lamp has will keep the rest of the wires from "letting out their smoke" as we call it. If the headlamp is lighted, you have a short. When the bulb goes out, you have no short. Once Ifound this out, many shorts were found in short time. We call it the Ol' Ugly. Hook up the Ol" Ugly and start to move those wires around. When the light goes out. Look in the area of where you were when it did. Works every time if you have the patience. David

great idea. I`ll be using this myself this afternoon for the short in my left taillight. Thank for the tip

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
