Hey guys I have 82 Euro 315 and i need help with the wiring diagram if anybody knows anything, your help would be greatly appreciated. thanks

What do you want to know?

How to wire up the lights. My driver light is brighter than the passenger on low beam, and the oppisite on high beam. and the rear lights do not work. The bulbs have been replaced and so have the fuses and i don't know what wire goes to what light. And my key igniton doesn't work but if i take a screwdriver and touch the two end on the starter it will turn over.

sounds like you have some interesting wiring issues.

For one, about the lights, I would check the ground connections, the brown wires. One set is near the battery, the other set is in front of the washer tank. You probably have a bad ground, or possibly a corroded connector at the headlights.

Its also possible that the ignition switch could be causing all the problems.

Any wire that's solid brown is a ground wire.

Headlights:

Left front low beam is a yellow/black wire

Left front high beam is a white/blue wire

Right front low beam is a yellow/blue wire

Right front high beam is a white/black wire

Parking Lights:

All lights on the right side of the vehicle are a gray/white wire including the license plate lights

All lights on the left side of the vehicle are gray/yellow

Front Fog Lights:

Left side is a yellow/brown wire
Right side is a yellow/violet wire

Reverse Lights are a blue/white wire

Brake Lights are a green/red wire

Turn Signals:

Right side: blue/black
Left Side: blue/red
