    For my 2002 Chev 2500HD, I found a CD set on FleaBay... presumably bootleg copies of GM dealer information. HAYNES diagrams were insufficient. Took a chance because of low price. CDs arrived ~7 days, shipped from Romania. Have not yet evaluated, but at least the CDs did arrive as promised.... YMMV = your mileage may vary, as they used to say. Good luck!

    I'm just guessing here but it sounds like your headlights and horn are grounding out your coil or distributor somehow. did you splice into any wires maybe thinking they for antoher system on the truck?
