Detonation / knock sensor wiring

06-02-2021, 01:03 PM

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.
