Help installing Bosch Knock sensors

[RZtwin]

Using Haltech 2500 Elite on my 2jzgte. Has anyone installed these 2 pin Bosch knock sensors to replace the JDM single wire ones? If yes can you tell/show me how you did?

Thanks:)

First, you will need some two wire shielded cable. Very important that these wires are shielded so the knock sensor signal does not get any sort of interference from other electronics. 

https://prowireusa.com/c-58-shielded-tefzel-cable.aspx 24 or 22AWG wire will be fine. Get around 4 meters so you have more than you need and you can cut the required length for each sensor. 

From toyota or the internet, grab two of these adapter studs. This will allow you to screw a stud into both knock sensor ports on the side of the 2JZ, then you can install your knock sensor to that stud. Tighten to around 15nm of torque. 

2 Wires needed for Bosch knock sensor.

1 Wire to Knock Signal, other wire to sensor ground.

Ground shield wire to chassis or power ground. 

Polarity does not matter. 

If you are running two knock sensors, you can have them share signal ground and shield ground. Knock signal must be independent.
