Hi everyone, I am new to the online prelude scene but have some decent experience working on them.
I am after making a Killswitch, I dont want to mess with the ignition yellow wire(is it the yellow wire?) since if something happens to my relay then the car will shut down in the middle of the road.
So I think I should take the starter motor route ? I am after something Homemade with a toggle switch a relay and some wire.. If anyone could give me some step by steps and a diagram or the color of the wire and stuff I have to do...

this question has probably been asked few times but Searching didnt answer what I was looking for. Can any one please help me out? I own a 4th gen if it helps.
