Hey guys had to get my car in for inspection and it needs a rear back up light switch. No power going to the switch apparently. Fuses are fine, and replaced bulbs with no luck. Anyone know where it's located and what kind of work is involved in it?

I have a full sub box and 2 amps in my trunk. Do they have to come out?

the switch is on the transmission.

Alright cool, thanks!

Its should be mounted roughly underneath the top left corner of your battery tray on the transmission.

Part number is 84210-12040
the gasket for it is 90430-18008

its 27.56 at 1sttoyotaparts! Just bought one recently.
