Yup its that easy, but you can be really smart, and have a panel with a button and a 2 flick switches with LED's on,
One you flick and a green LED comes on which is your ignition on, and the 2nd is an emergeny cutout that puts the system into what is key position 1
or just have the one switch

depends how good you are at electronics

As for the boot popper i did search but only in the mk3 section and the detailing parts but ill search the mk2 as well

Thanks
