On July 10 2004 my Chevrolet Silverado crew cab Duramax started on fire while sitting in my driveway. The milege was 47,800 miles. The insurance company hired a fire investigator who determined that one of the wiring harnesses following the drivers side frame rail at the firewall wore through or was frayed by the inner fender. The three harnesses are poorly supported on 2001 and 2002 diesel and gas trucks.
I have photographed several other trucks since with wear or exposed wires in these harnesses. The wires that were involved in the electrical fire have hardened "balls" on the conductor ends.We are in the process of determining which circuits conducted together. The trailer hitch wiring harness was not involved.
The electrical harness fire started the power brake assist hose on fire. The resulting fluid fire fully engulfed the truck in minutes at a total loss. I still have the truck in my possession and want to prevent this from happening to anyone else!
