Can we install a push start button in our gs300?

 

You can install a push start button in many cars. Just interrupt the starter wire and run a switch so you just push the button to complete the circuit. If you're talking about keyless push start button there's also a company that allows you to have transmitter like new cars and you can start it with a button. You'd have to bypass the locking mechanism on the steering wheel tho. I think there's a thread on myis where someone installed it on their 1st gen is300
