It all depend on how comfortable you are dealing with the electrical system.
Funny enough, my Subaru had daytime running lights and I went out of my way to GET RID OF THEM
I also did other electrical hacks such as hacking the hi-beam signal to allow me to use my fog lights at the same time as my high beams. hacking my side markers to blink with my blinkers, adding in some rear fog lights, replacing all of the green bulbs with blue LEDs in the gauges, HVAC, stereo, dome light, switches, etc... hacking the keyless entry system so that I could lock the doors from the fobb while the car was running (I had a turbo timer so locking while running was important) as well as hacking the keyless entry system to unlock all the doors in the car with a single button push instead of once for the driver and again for all passengers.
I'm fairly comfortable working with electrical systems though, and car electronics have a nice benefit of having fuses on everything... I've screwed up a few times... crossing the wrong wires etc. but the worst that has ever happened is a blown fuse. Of course they're always the risk of starting a fire or killing some component but on a whole it's safer to work with then most systems IMO.
as long as you've got a good wiring diagram (colors are key), pay attention, check and recheck everything you're doing... you should be fine.
