You can plug the green wires that are attached to the headlight shell nuts
INTO the green wire with dual recepticals. The front signals have two wires, one
go to each filament of the bulb. The bulb socket is then grounded thru the bulb housing/stem/the nut inside the shell/thru the green wire attached to the
nut, AND FINALLY TO the green wire with 2 recepticals. Gonna go out on a limb and say that should work. If not, a fuse should blow. Someone please correct me if I'm wrong. The two wires going to the front sigs are black wires with small bands that correspond with the like colored wires they connect to inside the shell.
Org/white bands go to org/white wire inside shell .....etc..
And if I'm reading the diagram right, the green wire shown in the diagram coming from each front signal light-------- IS THAT GREEN WIRE ATTACHED TO THE NUT IN THE HOUSING.....just emphasizing not yelling
