Hey guys,

Brand new to forum, have worked on and built trucks for some time though and could really use some help. Can anyone get me a wiring diagram for my 2015 F-150? I have recently lost my running tail lights and licence plate lamps. Visually checked every fuse and found no problems there. I put in LED tail lights a couple weeks ago and they worked fine then noticed one day my tail lights weren't on when headlights were. Front running lights work fine. If I could get a diagram to start tracing wiring back that would be greatly appreciated. Thanks so much.

 

Also can anyone verify I am checking the correct fuse? The manual does not list any fuses directly for brake lights in truck!

 

Good question...bump for you!

 

Thanks! I am completely baffled. Brake signals and turn signals work fine also and I did all the work to my truck myself (6" lift, HID's, exhaust, LED tails and so forth) so I know the work was done very carefully which should eliminate a cut wire

 

Aren't the LED tail lights just plug in? Have you tried just putting the original incandescent ones back?

 

Yes I have and same problem. Only brake lights and turn signal work. No running lights. I also plugged my led tails into another 2015 f150 and they worked fine

 

Don't just visually inspect the fuses - check them with a continuity tester. I've seen fuses that looked perfect but were actually blown.

 

Thats a good point, thanks. Can anyone tell me the number of the fuses I should check with my multimeter? I don't mean to sound like a newbie but the manual is not clear at all and only lights referred to are for trailer lights?

 

Also, in the same time frame that my tail lights stopped working, my door chime started going off when I put the truck in reverse. Could they be related?

 

Wha? You need an electrician. Door chime alarms when you're in reverse?!? You've got electrical gremlins. If the truck is still in warranty, you ought to just take it to the dealer.

 

Yeah I was backing up with my door open in the rain and it was chiming cause the door was open and its been chiming ever since no matter what. All the warranty have been voided though with all the work done to the truck

 

Worth a try. Let them look at it and tell you it's voided.

 

Will do thanks I'llooks post what happens

 

Okay so dealer diagnosed problem to be one light was bad and grounding out the whole system and would trip some module so as soon as I turned key to diagnose the electricals it was already messed up. frustrating but good spend of a 100$! Now to fix the weird chimes. Sometimes when I put the key in with the door open, both chimes go off (like the high pitched chime from the cluster and the deeper chime in the speakers). still goes into chime while in reverse. Anyone have any ideas? I have no problems pulling apart the cluster and disabling the chime by cutting wires if that will work

 

+GlueGuy do you have any ideas? The truck was from canada so I put in a new identical cluster with MPH but other than that everything is stock.
