Wiring LED tail lights

[yahrt]

my Everest during this build is going to be wiring, here goes, complete kit MKIV, just received tail lights (United Pacific LEDs, three wires), before they arrived was thinking I would be using the supplied converters, but now I am not sure, and am struggling to find the necessary info, thanks for any help

If you are talking about taillights you need the adapter and electronic flashers .

I kept it simple and just replaced the bulbs in the existing tail lights and turn signal housings with 1157 LED bulbs. The only other change required was a couple of inexpensive LED compatible flashers for the fuse box.

I'm still confused, the FFR square LED tail light has three wires (red, white, black), the FFR supplied converter has 4 wires on the car side and 5 wires on the trailer side, the wiring harness has 4 wires, how does it all go together?
