I plan on installing a killswitch in my 2022 ES350. Does anyone have any experience doing this?

Whats the best approach to fishing wires through the firewall if I wanted to switch the fuel pump fuse or relay?

 

you can use a wire hangar straightened out and a piece of electrical tape.

maybe install the switch in-line with the fuel pump fuse/relay? but make sure those connections are super duper high quality.

just a hunch on where i'd start. there possibly might be better ways in 2023!

 

Explain, please. What and why?

 

its an old trick used for about 40-50 years so people dont steal a car. just wanted to respond to OP since no one replied to him for a few days. so i put it to the top

 

Are you worried someone will hot-wire your car? Or get access to your key? The car already has built-in security against hot-wiring.

 

I'm more concerned about a can bus attack:

I'm going to be traveling to a city with a high rate of vehicle theft in a few months so I was planning to install a switch on the fuel pump... but how often are ESs stolen? I know Lexus SUVs are commonly targeted but does anyone care about the sedans?
