I have a set of European taillights I bought from Jeep Village (Jeep Village, Index
) in France. The OEM North American tailight uses three wires on the four-pin connector while the Euro one has four wires. The connectors are exactly the same and amazingly the European model must have a different wiring harness as for example the back-up lights are on a different pin. They also do not have the side marker light as that is located somewhere else on a Euro TJ. The lights are a bit deeper and of course they are made in the USA (Crown Automotive Sales, part number 5764204).
It appears that to make them work I will have to run a separate circuit from the brake light switch on the bake pedal, disconnecting it from the existing harness, to the rear taillights as well as the high mounted rear brake light. The problem is that in the OEM North American light the turn indicators and the brake light share the same filament.
If I had to do it over again I would just spend around the same money and buy a set of JeepLEDlights. I would be done in 60 seconds but I must admit the amber section looks pretty cool.
