Wiring question - 1999 F250 with 2015 bed/tail lights

I have a 99 F250 truck, 2015 bed on it. Bed came with the tails and a chopped harness that appears to have 5 wires.

The pigtail from the 99 harness has 6 wires.

I have been unsuccessful on finding the color of wires for the 2015.

I'm not the smartest when it comes to wiring, so if someone has a chart or diagram it would be awesome!

Have you checked yet the wire color may be similar...Also there are prob trailer wire in there on the 99.

brown park lights, yellow left. green right or light blue.


You can't hurt anything if you try hooking them up...Just watch out for black as its ground. you don't want to blow fuses..

Maybe hook up the two black wires first.

Thanks!

I have found a few things that show the colors for the 99, but nothing for the 2015. I'm still looking, please don't think I'm not trying

I do, but they are completely different colors on a harness/plug.

Sorry for the noob questions!

I'm unfamiliar with how the tails operate? Do they have a 12v+ feed and then everything else works on grounding the wire ? If I can find the 12V + for the 2015 tails then I should be able to trial and error the rest without popping a million fuses.

like red and br/w and dark blue brakes////white. these are for trailer.

Should only need 3 wires to get the bed lights working....brown.TAIL LIGHT ... LG/O LEFT O/LB RT FROM THE 99

12 volts nope just those 3 wires and the ground black.

Find the black wires connect those first... Connect the ground wire to the frame where it was...
brown wire to brown.....check park lights work

Fixed, now I just need to crimp/shrink it together.

Thanks again 99f350sd

For anyone searching for this in the future:


99'
F250 to 2014 f250 tail lights

Grn/Or - Grey/Blue
Black/grey - Blue/yelw
Or/blue - Purple/Yelw
Blck - Blk/wht
Brwn/?? - Yelw/grn

I apologize if the tracer colors are incorrect, but I didn't spend a whole bunch of time cleaning them up. There is a tag light bulb that will need to get spliced in to the park lights, I believe that is the Brwn 99 side and the yellow 14' side.
