Knock sensors codes P0332 and PO327

I replaced the knock sensors with su7012 instead of su7015 sensors. I was informed they are the same except the 7012 sensors are 3 inches longer. After replacing them, nothing has changed. Vehicle still runs rough and reads restricted performance along with engine light. When thermostat housing was changed hose was not connected and coolant ran out everywhere. Please tell me what the problem could be. Did I damage sensors when putting them in
