main wire harness runs under driver's seat and plugs into the floor in front of rear seat. The connection inside the van and underneath connectors are corroded. THERE IS A SMALL PLATE COVERING THE INSIDE CONNECIION. This is an easy removal. simply drill out two rivets and the plate comes off. Finding a non-corroded connection in a junk yard is difficult.
