Installing a back up beeper

Good afternoon gentleman

I work for a higher learning entity and we have 2 (two) - 2024 Tacoma 4x2 XTRACAB pick-ups we are adding to our fleet. For bystander safety, we have to add external back-up beepers to the vehicles. Multiple questions follow: does this generation Tacoma have all aluminum wiring? Has anyone ever added an external beeper to a 2024 Tacoma with LED tail and reverse lights? Is it safe for the circuit board to splice in a tap for the beeper? These trucks did come with the trailer hitch and wired for a 7 prong/4 prong trailer connector. would it be safer to tap into the trailer plug connector for the reverse lights? Any help is appreciated!

Thank you,

Purchase the matching wire to wire the beeper.
