Car - 1988 Kouki Levin coupe

motor - Bigport 4AGE

problem - Reverse lights not working

personal situation - My reverse lights havent been working for a while now. I replaced the lamps in them, but still no luck. Got an auto sparky to have a quick look at it and he confirmed that the problem was the reverse light switch.

Ive since bought a new reverse light switch. Just wanting to know if anyone has changed one before? Where abouts are they located? Whats the best way to go about it? Easy enough to do in my driveway?

Cheers, Shawn.
