just put the damn switch under the dash and run the lights to it....DONE in 5-30 min
when you sell the car nobody will see the holes. How much do you think the two littles holes somewhere would hurt the resale value? These cars don't have good resale values anyways....how much did you pay for your car? 1000-1400 i'm guessing. 160k on a car people aren't looking for mint condition....they're typically just looking for anything they can afford.
