After taking the rear tail light clusters off of my MK2 Clio Campus Sport to clean out the dirt, I noticed that the drivers side tail light cluster had an extra wire hardwired into it as well as the usual wiring plug which can be disconnected. Taking the bulb assembly out, there is a wire soldered directly onto the board just below the top bulb, think its the fog light. Tracing it back through, it looks like it has been spliced into the ground wire which is bolted to the rear of the car. I was wondering if anyone would know why this would be done? I have attached a picture to this post
