Knock Sensor Upgrade Kit for 95 850 Turbo 850 1995

I have purchased the upgraded knock sensor kit with new wiring. However, I cannot find a copy of the TSB that gives installation instructions. Does someone have a copy of the TSB that they can email to me or give me general instrucion on how to do the installation. I have the intake off. The new knock sensors are ready to go on, I just don't know which one should be the one in the front. I and I not sure how to deal with the wiring and the white bracket.

Thanks
