Where exactly is the main ground cable located on my 98' 24 valve? And is there more than 1? My headlights are dimmer than congress:lol: and I was told to check my ground cable.

Headlight ground is inside the cab under the the driver side kick panel. But I've got a feeling you blew the head light fuses. Main battery cables are off of both batteries to the engine driver and passenger sides.

Ok, but if it was the fuses the headlights wouldn't work at all, correct?

No they appear dim because the draw power from other sources and tend to illuminate both elements of the bulb giving a dim appearance. Headlight on our trucks are backwards to what you think. Battery (+) -> Fuse (L & R) -> Headlight -> Multifunction Switch -> Headlight Switch -> Ground (-) So the headlight typically have 12 volt power all the time its just the ground is turned off and on.

Well the fuse is good. I'm assuming that there is only the one that I found under the hood. I looked for that ground but couldn't locate it. You say the kick plate on drivers side, are you talking behind or beside the pedals?
