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. |

I have a switch for the fuel pump and auxiliary oil cooler fan. Both are in plain sight and unlabelled on the dash (plus, I have a battery disconnect for storage and electrical work). More than once I have forgotten to turn on the fuel pump only to have the engine die shortly (carbs). Fooled myself several times thinking something failed because I forgot about the switch - D'oh!
Maybe reconnect the the seatbelt interlock under the passenger seat that most have defeated (by connecting the yellow wires together). Then mount the switch under the passenger seat. Nothing under the dash to worry about in that case. Not sure if the '73 had the interlock... |
