Im preparing to install turn signals on my truck.

I have the old signal lever that was in the truck from way back.

old signal lever pic

Going to clean it up and try to install it if its still working.

Heres a pic of the back
Back of signal

Since I have no diagram can some one tell me if the
Yellow/green would be one side (ie left front and back)
and white/red be the other. Or something else.

It has 7 wires
red
green
yellow
white

black
orange
brown
I know the orange and black go to the flasher

any help would be great. I do have a replacement on hand (Taiwan)

Thank you
