if im not wrong, you only mess with waranty on the parts you mess with.. so head unit and all that stuff

if wire are cut, then the entire electronic warranty is gone

inkambing 52k wire loom 

oh wait, wrong car

Just choose accessory which plug and play with no wire cut

Any warranty claim on parts that uses wiring..will be voided.
But u can claim for other parts like transmission, engine, steering rack etc.

Alternatively if you bump into a sc that doesn't make claim for your warranty parts, u can always try a few more SCS. No harm.
That's if you don't stupidly go claim your audio quality rosak when u switched your original parts out..
