I recently rewired my trailer lights to a 4 prong trailer light connection and it took me forever to find a thread that had the wire colors in the rear and what function each wire color performed so I just wanted to repost this for anyone who might be tackling the same project... It is spring time and boat/camper pulling season is upon us!

Black - Ground
Red/Orange - RH Tail
Green/Purple - Stop Lights
Green/White - RH Indicator
Green/Red - LH Indicator
Red/Yellow - Rear Fog
Red/Black - LH Tai

If anyone would like Ill be happy to post pictures and give a diagram to what wire went to what on the 4 prong system, just let me know!

 

There are two others that may be of use.
Single Pin Socket A:
Green/Brown - Reversing light

Single Pin Socket B: 20A fuse F6 in Satellite 2 (I think)
Purple/Brown - Power
(I connected to this to supply power for the battery for the break-a-way trailer brake controller)

I used a converter to change the turn signal and brake lights being on separate wires to a 4 pin plug. I got the converter on Amazon.

 

Nice! Yes there are a lot of good converter options out there that I would have loved to take advantage of; and i recommend everyone does a conversion rather than dicing and splicing. Unfortunately, I bought my Disco used and someone had already attempted to rewire the trailer connection and the wires were just left strung out so I had no choice but to hardwire in my own connection

 

I used a uhaul one on mine. Works great.
