until I switch engine off and restart, #5 mini fuse (15 amp) blows and  I am back

Pull the fuse before you start it, if it starts and runs, put in the fuse. If it doesn't blow, your good to go. I realize that isn't the proper fix. Note the diagram. That K goes to drl. If it is wiring circuit and not component, it's like hunting a needle in a hay stack. If you can find splice 222 and disconnect there, it might tell you something? I have location for connectors but not splices. good luck
