A condition may exist on certain 1988 K models where the front drive axle wiring harness is routed too close to the right exhaust manifold. Due to high manifold temperature, the harness may become damaged. To repair this condition, a nylon tie strap, P/N 3816659, has been released to hold the harness away from the exhaust manifold.
