Tail & marker lights inop, HELP
2001 Ford E450, 7.3 turbo superduty diesel , 92k. Upon demo Iíve managed to somehow disconnect power to both my tail and marker lights (both front and back). I followed the power feed line and it looks like all these lights are ran in series off of one wire. All my other lights work - headlights, brake, turn and reverse all ops check good. Iíve checked all my fuses, both under hood and under steering column. I also checked the relay and it does click when I pull the light switch, leading me to believe the relay is good. All lights are also grounded properly. Any help is much appreciated!
