I'm pretty sure you can pick up an pre made adapter at any of the chain auto parts stores like Pep, Napa, Auto Zone etc.
Sure will make your life a lot easier than trying to rig something ad hoc.
yellow is left signal and green is right signal. I think the adaptor is to go from 6 or 7 round on the truck to 4 wire flat on a trailer. I don't think they make it the other way but might be wrong.

gReen - Right
yeLLow - Left
brown - tail
white - ground
The blacks could be brake, reverse, or charge( for elec, brakeaway brake battery). You can find the brake one by puting power to it, the magnets will put out a small hum. Maybe you don't have reverse lights, but I don't know that. Good luck:)
