how to hard wire line of fire

i ordered recon line of fire and would like to know if i could hard wire into the towing harness? not sure of schematics of color codes on wires etc.....does any know which wires are for ground, hot, neutral, and colors for right signal, left, and back up? thanks in advance.

I'm colorblind, but I would use a test light to find out what wires are for what.
