I have gotten some work done in the past days. Since this is an american car made for the american market it needs some modifications before it can pass an inspection in Sweden.
One major issue is the lights. In Sweden (and the rest of Europe??), the turn signal must be yellow, the daytime running light has to be white and the car must be equipped with turn signal lights on the front fenders.
In order to "fool" the system, I have used the turn signal that goes to the front turn signal and have connected it to a relay.
This means that the car does not "see" the new turn signals. If I was to just parallell-wire the new turn signal the turn signal would blink very slowly or the car would register the extra amps needed as a fault in the circuit.
I then connected my new turn signal to turn signal lights at the front fender
And then to the rear turn signal light, I purchased a used wire harness which was modified to fit the ugly Euro outer rear tail lights.
The original rear turn signal and brake light signal is now disconnected and in order to avoid a fast-repeating turn signal I have to simulate the org lights. For this I used resistors mounted on metal plates to keep them cool.
I now have the turning signals the way i want them, but no brake signal. In the last picture you can see the relay for the new brake signal, for this I used the signal from the trunk brake light.
This only leaves the yellow daytime running light which I simply disconnected with new connectors.
All of the cutting of the org harnesses has been done so that it can all be connected back to its original shape using the water-tight connectors.
