I have a 1990 740 gl wagon. I am replacing the passenger side tail light assembly. I have the new assembly. The bulbs have been replaced and moved over. But like an idiot I didn’t take a picture of the wires and placement of wires before unplugging from the original tail light assembly.

does anyone know which wires go to which lights?

thank you in advance.

 

Take off opposite side bit keep wires intact. Should be Oem france with color coding to match. Remove bolts but keep wires installed... Should have enough room easily.

thanks. The problem is the drivers side is different. 8 wires verses 6 and the colors are different.

 

Different because of the fog light. Take a multimeter and use it to determine what has power when various things are turned on... not that hard.
