IS 200t After market Ignition Lock

[Bart34]

Hello everyone ! Going to install some after market Ignition Lock for my IS 200t 2017 , looking for some electrical diagrams for Engine ECU etc, I am searching for two days and really can't find anything which could be usefull, maybe you have some better expierience in that ? Also looking for some inspiration which electrical circuit would be the best to "block"  maybe some connected with engine start-up? Thank's a lot

I would think very carefully before you start breaking into circuits and adding non OEM devices, the standard fit alarm immobiliser should provide adequate theft protection. With modern car electronics and Can bus you could end up in a mess if the circuit you modify supplies another essential ECU.

If you do need additional theft protection consider a steering wheel lock or wheel clamp both of which are quick and easy to fit and remove plus a visible deterrent.
