95 V6 Knock sensor issues

[shotwell]

Trying to figure out a 1995 4Runner V6 Auto with a knock sensor no signal code.

Just replaced the engine. Also replaced the wire that goes under the lower intake. Did NOT replace the sensor.

What I'm trying to figure out before I tear the motor back down is how to test the wire harness. I need to know what signal the computer is sending through those two wires so I can attempt to measure it. No signal = bad harness. Good signal = bad knock sensor.

ANY help would be greatly appreciated.

I really need some help with this guys. I don't want to tear down the motor again to find out my wire harness is bad.

Where else can I look for this information if no one here knows it?

Usually the coax knock sensor wire harness corrodes/rust where it meets the passenger side floor near the ECU (EFI computer).
