If your wiring has become a desperate thing, you can replace it with a brand new wiring loom.
This wiring set is the complete main wiring harness from the dashboard to the rear, with all mounted connectors. The wiring harness has a casing like the original so the wires stay together.
The wiring set is also provided with a clear wiring diagram (equal to the original, with the original color codes).
