Volvo: 91 740 volvo running lights, fog light switch, fog light installation

Question
Hi Ray, the right front turn and right rear running lights are not operating unless I turn on the fog light switch on dash. I've checked cleaned all bulbs and connectors front and rear with no effect also checked fuses, all good. Could it be a relay? Also when I do turn on the fog switch the wrong right rear bulbs illuminate. All was fine till after I attempted to wire in under bumber drive lights attatched to existing fog connectors. Any Ideas?    Thanks, Ed

Answer
Ed,
Since all the trouble started after the fog light installation go back and disconnect the wiring and see if all lights work. If they do you know that the installation was at fault. Redo the fog lights and see what happens. That failing get some help from a tech that knows Volvo's so you are sure of the wiring that you have done.
