Hey Jesse. The functions of the individual wires for the Replacement Bulb and Socket for Blue Ox Tail Light Wiring Kit - Qty 1 item # 294-0774 are listed below:
Black Wire: Brake / Turn Signal Light
Brown Wire: Tail Light
White Wire: Ground
You'll need to use a circuit tester like item # PTW2993 to determine the functions of your tail light wires to splice into the correct ones.
Do you need any other parts to flat tow your 1998 Toyota Tacoma?
