Focus Estate Mk2 Rear Lights

[ffocus]

Hi guys,

I'm trying to replace rear lights on MK2 LHD estate with RHD ones but not to sure how to go about swapping the fog light with reverse. On some models the wires for both are fitted to both sides in the wiring loom so the appropriate lamp unit just connects to the wires needed. Is it the same case with Focus? If not have you got suggestions how to change them without having to rewire the whole lot.
