Okay guys while driving my guages and dash lights dim mostly when i het a rough bump they swing to the left and go dark then I hit another bump and they swing back to normal with the lights going back on. I have checked battery cables they are good I dont think it is the alternator just because it seems when i hit a bump is when i have the problems so i figure its a lose wire or somthing in the dash have any of you had this problem before and where could i find a wiring diagram? Any help will be greatly appreciated.

check the grounds, I think they are on the back of the engine head. But there may be one or two in the cab as well. Check the wiring diagrams in my sig.
