I'm not getting power to just the rear passenger turn signal & hazard socket. I first tired a new bulb & then tested with meter. I also replaced the multi switch in the steering column - and that also didn't help. Last month I had noticed a loose (pink & Black) wire under my ignition switch -- but honestly I think the turn signal was still working fine after I found that loose wire. Some background info -- my Father bought this new -- never did any work on it -- nor added any after market alarms etc -- but I have only had it this since Feb -- it is a 2002 Expedition with 5.4L 180,000

 

I checked the loose wire and it has power -- I still have no idea what it is. There is not any continuity between it and the rear flasher/turn signal socket that is not working

 

IIRC, the Black/Violet wire is for the key-in-ignition alarm, circuit.

 

That is great -- thanks very much -- I capped it off -- Do you think I can I live without that alarm -- could I get away with leaving that wire disconnected?

 

I have for years. You just loose the warning buzzer that would otherwise go off right before you locked the keys in the truck.
