Default Knock sensors are they the same

Hi guys I have to knock sensors gone .so I went on eBay and found a breaker who had a set but off another model.he said they would fit but I would have to change the connection fittings for mine.so I brought them cut off his plug and fitted mine in place.bolted them back on and still the same.3000rpm . So put diagnostic on and came up with input to high on one and low input on other one.so can they fit different cars or do you have to have the exact one taken off . Just need to know so I can eliminate there faulty

Jaguar # LCA1692AE looks to be the X308 number for all years and countries . Have you swapped wire polarities as you adapted connector differences ? Reset / cleared codes ? Impedance matching between different part numbers I would think is important as it is basically a microphone .

Seems like a lot of work when the $29 Duralast SU7012 from Autozone or the like are interchangeable.
