Picking up the truck next month so cant see exactly what the wires do but it will be freshly imported so will need to do a few things for its first mot - over 10 years so no iva needed. I am in the far north of Scotland and dont fancy having the truck shipped twice for the sake of some lights getting converted.

Foglight is going to just be on a toggle switch which is super easy. Front lights have 4x6 sealed beams so will just swap to uk ones for beam pattern which again is easy.

What is the best way to go about wiring up rear lights for the uk?



I assume amber bulbs where reverse lights were is the easy bit as they arent required. Brake lights/indicators share a single wire. Do I run cables from front indicators to back, run cable from 3rd high level brake light back to the bulbs and then just leave the old brakelight/indicator or even just a resistor plugged in hidden away so it doesnt flash quickly? I would fit led bulbs all round as to keep the voltage down to trick the computer into not seeing a issue with extra power draw - might even have to add resisters to bring the draw up again.

Ford with a smart junction box for the lighting which google suggests is pretty funny with changing stuff about or I would just run fresh wires and not question it.

A different thought was a 2 way to 3 way converter such as this cheap looking thing for trailers. Not sure how it works with the hazard lights though as it says it will flash your brake lights.

They split up the brake light/indicator signals internally using voodoo magic.
