Got mine all wired up and compressor won't turn on. I have a wiring diagram and directions on compressor wiring. They both say something different. I don't know what it could be
... good thing to "jump"! :o The pump is located on the inside of the drivers side frame rail, just about where the cab ends. I don't have a diagram that shows the feed and return lines or the pin-outs for it.
... If anyone has any questions feel free to ask. Did you install a boost valve? How did you get the electronic switch out of the way? Because the diagram it came with did not show any electronic plug in front of the boost valve/pump. Thanks
