Hi Team,

I've a 1990 TT and I've just stripped the engine. My question is the plug was missing from the knock sensor so I've repaired the wires and just put a single small "lucar" connector. I say single because although 2 wires come from the top the black wire folds up and is taped in against itself.

Is this right or should 2 wires go to the sensor?

If it has just one wire which side does it goto as you look at the sensor?

Any ideas?

regards,

Jase

Its just the 1 wire...from memory the White one goes to the Det sensor and the Black wire is not connected but acts as a shield.

 

Although I could'nt tell you which side Im afraid without looking and I've removed mine so I cant help further....

hope this helps you out

 

 

Only one wire is connected.As stated by Legrath the other wire is for shielding like co ax and shrouds the inner.

oh ok scrap the black wire in the picture then:tongue::tongue:

same on the o2 sensor connectors, im sure

^^^^^ They are shielded as well mate your right.The outer core is grounded at the ecu IIRC.pretty hi tech for an old motor !!
