Nope, nothing will happen when you install the HIDs in terms of your other electronics. Just make sure you disconnect the negative terminal of the battery before installing them.
This car is a little different in the design of how the headlight bulbs are placed as there is only one wire from the headlight assembly to the car whereas other cars have separate wires for each bulb. To install the HIDs, you will have to install a ~1" hole in the dust cap.
Here's a good DIY that you could follow.

If you don't feel confident doing HIDs yourself you could find an installer or depending on where you live, a forum member may help you install them also.
