I am having problems with my tail and rear marker lights.  When I switch on the head and tail lights the only lights that come on are the two front marker lights.  I replaced both reaer tail lights and both the break and turn signal work in them.  I also replaced the 7 pin cable.  I checked the green wires there and they all look fine.  I also checked the ground there too and it is fine.  What is the next thing to check?  It looked like one of the rear side marker lights had been replaced so I took it off to check the wiring there and it was good.  Thanks for your help.
