First I'll try to explain what I'm looking at because I don't have my digital camera handy. Following the vacuum line from the pump it leads to a distribution block of sorts. From that, there is a short line that runs to a disc shaped object that is fastened to the driver side wheel well. This object has what looks like 3 wires coming out of it that lead to a larger bundle of wires then into the fuse box under the hood.
I noticed that a nearby wire bundle has rubbed a hole in the insulation of the wires coming out of that disc shaped object. But I don't know what that little disc shaped deal does! Everything is running as usual but I'm wondering if I should dig into trying to replace the disc deal and it's wire or just tape over the hole and see what happens on down the road.
Apart from the usually reported sinking brake pedal problem associated with these trucks, my vacuum system seems to be fine. But it would be nice to find a diagram of that system to see what this little disc gadget does!!
Any ideas?
