One problem related to underhood wiring has been reported for the 1998 Dodge Ram 1500. The most recently reported issues are listed below.
My son was driving on hwy 78 when the pickup lunged a couple of times. He was going to pull off the road to check for a problem. He had the cruise set so he thought it might be transmission problems. He looked in the rear view mirror for traffic behind him and saw flames and smoke coming from between the cab and the bed. He immediately pulled off and told his finance to get her baby out because they were on fire. When he opened his door the flames errupted into the cab and he had dive out through the flames. The pickup exploded about one minute after they got out. They lost everything in the truck.
