For a 1995 Ford F-250 that never had trailer wiring you will first need to install # 118316. Then you can install the 4- and 7-way installation kit # ETBC7. The other option is to use a circuit tester like # PTW2993 if needed to determine the functions of the wires you have found and hardwire them to the ETBC7 by cutting off the 4-Way end and splicing on the truck wires. On the ETBC7 4-Way, brown is running lights, green is right turn and brake lights and yellow is left turn and brake lights. Doing it this way, if the wires you found have the proper functions, would mean that you do not have to use the 118316.
The ETBC7 provides the 7-Way and the wiring needed to install the brake controller. I have included some links that will help with the installation.
