Detonation / knock sensor wiring


  • Detonation / knock sensor wiring

    I recently bought an 86 Turbo. It is sometimes hard to start when cold.

    I adjusted the TPS. In researching the detonation sensor, it looks like it may be unplugged (see attached photo). Can anyone tell me where I should be looking for the female end of this plug? And/or what it might look like?

    iirc, the detonation sensor is a single wire that has a pinch&pull white plastic shroud that acts as a strain relief and locking mechanism to keep the bare terminal in your photo secured into the sensor.
    I think the whole thing is covered by a large grey vinyl boot, like the oil pressure sender.
