Subaru Wrx6x Bosch wideband knock install help

[kayzarh]

Hi, 

Wondering what is the best way to install this sensor. 

Do I run a 2 score shield cable back to ECU area and then pin into the expansion connector?

I am planning to run ground and power expansion into engine bay for some additional sensors, 2 combined Bosch pressure temp sensors and a link IAT sensor.

Please can you advise best install method to get cleanest knock signal

For the Knock sensor, wire it to the same pins the factory sensor used.  Knock ground and shield both to B136-29, knock signal to B136-26

Based on this, is it worth me going to a Bosch wideband knock sensor or is the 1 pin style v7 sensor sufficient for knock detection on a 2.5 engine with forged pistons?

I have no idea, I suspect if it is a resonant frequency sensor from a different sized engine it is probably not going to be ideal.

If I use the factory 2007 knock sensor which was on the 2.5 engine?

That would probably be the better option if you want to stick with OEM stuff.  I have no experience with that specific engine or sensor.
