Ok, I just broke down and went and got a voltage tester and I found out that that wire acutally goes to this

What is it? It may be a stupid question, but it's imperitive that I have all the wires right for my ECU to work correctly.

The VTEC and VTEC oil pressure wires are actually on the other bundle that goes into the other large connector on that side of the harness.

Where is the knock sensor located on the motor? I thought it was white and on the intake??? Any help would be great!!!
