97 and up prelude knock sensor... are they 2 wire knock sensors?

I know that all B series are one wire knock sensors and that 92-95 preludes are 1 wire knock sensors... but whats this 2 wire garbage im hearing about? What other Honda/Acura's have 2 wire knock sensors?

 

Don't remeber if my 98 block was one wire or two, but my knock sensor broke, so I used one from my friends b18c5 and it work fine.

 

hrm b18c5 is 1 wire

 

I just called up a few honda dealerships

it is 2 wire *grumble* stupid dealership sent me the wrong one
