    Hey I’m not getting no 5v signal to my throttle body. The fuse is ok but I believe it’s the under dash wiring. Can someone help with the wiring diagram

    The EWD's are up there ^^

    But let me ask: Have you checked all the fuses under the hood, in the fusebox next to the battery, and under the dash? Not being a smartass, some people in the past have said "yes", only to find out pages later that they only checked the fusebox in the dash.

    You failed to mention which engine your truck has (V6 or V8, that's extremely important info), so I can't say exactly which fuses to check.
