Barry, Assuming you're using a flat, four-wire connector for a trailer that
doesn't require electric brakes, AND . . . the towing vehicle and the
trailer use a combined stop/turn filament in the tail lights, the
connections are;
Ground - white
Taillights - brown
Left signal - yellow
Right signal - green
This color code is an SAE standard and the bubble packs with the harness
frequently put the color code on the back. This is so that your harness will
have a better chance of plugging into your buddy's trailer and vice-versa.
Here's a link:

Then technical departments - trailer wiring
The best place to hook up this type of connector is at the rear of the
vehicle at the taillight harness, once you have determined which wire on the
vehicle does what.
For a 50-watt lamp: assuming 12 volts DC, the current draw will be just over
4 amps. 16-gage wire should handle this but I usually don't go below 14-gage
"just because".

Thanks for the info. I bought the 7->4 adapter a while back, and that has worked every time I have needed it to. The light question was just as a temporary "light up next to the truck as a work-light type of arrangement."
