Re:heated o2 and knock sensor

"it only has one wire" you just proved me right, it has to make its own voltage because it only has 1 wire going to it, lets look at it, it would not be a + wire, it would not be a - wire, so it has to be a single wire to tell the computer that it has knock, so when knock happens it makes its own AC voltage to let the computer know. trust me i have my ASE sert. in electril

so you are saying that since I am using a p28 ecu on my b16 that has a knock sensor, it would not work even if I wired it in, and put a chip that requires the knock sensor in. will it work or not?
