Just wanted to see if anyone else knew. All the research I have done says that a JDM GSR ecu has a knock sensor provision. However, when I did my swap, I found out that the knock sensor had been broken when the swap was removed. Started the car and had an engine light for VTEC solenoid but not for knock sensor. Fixed VTEC solenoid and there is NO engine light now and the knock sensor wire is just hanging there.

Any ideas?
