When attempting to replace the gauge in the truck ( which none of the gauges worked) the wiring seems to vary.

    No way this is right?

    Hello everyone, I recently purchased a 1978 GMC C2500 Sierra Grande and I have been fixing it up these past couple months. I’m not sure if the engine itself is original, but do believe the serpentine to be from a 1994-ish small block. I am now stepping into some territory that I’m learning as...
