If you have Lucas assemblies, there are three loops to tie wires to: running or parking lights, Stop and/or turn and ground. The large brass looking loop is the ground. With the assembly face down and the ground loop at 12:00, the loop to the right is Stop/Turn.

All of the assemblies take 1157 bulb and have glass lenses. If you run 2057 bulbs on plastic lense cars, you may have a thermal event where the lense disorts or melts. But, if they are lucas and glass, the 2057 will give a marginally brighter ( viewed straigh in ) illumination.

Wire color codes are for the rear as follows: White is ground, Yellow is left stop/turn, brown is running/parking and green is right stop/turn.
