Hi there!
I'm a newbie to the forum and quite a newbie to the E85 platform but I love it!
Since I own the USDM car I have to perform some modifications to legalize it in the EU. The main concern now is the rear fog lights (tail lights are replaced with EU ones, front - with halo aftermarket).
I have the light switch module with the front fog light button only. I know it is used as the backup storage for various car data so not plug-and-play replaceable. Has someone tried to replace the light switch module and reprogram it using the manual from the thread? I assume the data from the original module should be written to the new one and the main ECU should be programmed to recognize the rear fog light option. Do I have to rewire/add some wire in addition to the reprogramming?
Any hints would be greatly appreciated!
