i am currently in the process of an LS VTEC build up i was told that i have to wire in a knock sensor. i know i have to wire up the vtec to the ecu thats no problem but what wires do i need to splice the knock sensor into and or do i just wire it to the pcm. i would also appreciate it if someone could tell me or show me a picture of the pin spaces for the wiring for the vtec and or knock sensor.....
