So I want to install a switch hidden under the dash to stop the engine starting.
Having done a search, the black/purple wire going to the tachometer seemed a likely candidate to break the circuit. However, when I disconnected it from the tach, the car would still start! Which wire should I use? The engine is a 1973 2.0 four cylinder with fuel injection. |

Problem is all the important wires are in the engine bay.
I don't remember if the 73 has the seat belt relay under the pass seat, but that would be easy to tap into. Both engine power and start go thru it. If you install a start relay, like you should anyway, it will be a low load and any switch will suffice. |
