Just inherited a 90 454ss. One fog light out; figured bulb burnt out. Bulb was good. In mean time other light stopped working. That bulb is good also. Looking at wiring diagram my next thing to check was fuse. But noticed there is no fuse in the box for fog lamps. No inline fuse that I can find. According to wiring diagram there is suppose to be a orange wire from fog light relay to a fuse. Grounds seem to be good. Maybe replay? How can I check that before spending money on something I dont need. Any thoughts as too what I should look for next? I hate wiring problems. Thanks
