Then you simply put the ultrasonic module in place (it snaps in) and reinstall the dome light fixture into the car, taking care to connect the original wiring harness for the lights, and the previously unused one that snaps in to the awaiting ultrasonic module you just installed:įor the next step, open the hood (or "bonnet" for you English-English speakers) and locate the hood switch wiring along the drivers side edge of the engine compartment.

I did one side, and then held it with my hand and did the other side. There is a release tab immediately behind each circular light, and you have to get the pry tool in just the right place. (really, I am serious about this) The spot to pry is immediately behind each reading light, at the back edge of the fixture. When you do this MAKE SURE your hands are very clean, as you will stain your headliner if they are not. This was not specified in the instructions, and I spent about 1 hour figuring out that the front light fixture was not correct! To remove the rear dome light fixture, I used a plastic spatula as a pry tool so as not to damage the headliner or plastic. Make sure you do the REAR one (aft of the sunroof).

If you have any doubts about your ability to safely lift your car with a jack, do not attempt this install. Since our cars do not come with a jack, you have to use your own (or buy the BMW jack), and there are special lift points that require a special fitting so as not to damage the lift point (nice work BMW). The "hardest" part is removing the left rear wheel to install the siren. I would say that it is an easy install, as long as you have some mechanical confidence and experience.
