    Knock sensor is to be installed on the passenger side of the engine block mid-way beneath your exhaust manifold. Just remove the existing bolt from the block (will just be sitting there holding nothing in place). Shielded end of the harness connects to the knock sensor. Disconnect you battery (VERY IMPORTANT!!) and remove passenger side kick panel. Feed the harness through the firewall into the kick panel area. Unhook the computer and install the exposed pin on the end of the harness into the following pin location on the computer:

    B11 for all manuals VN to VSII
    B11 for auto VN
    D5 for auto VR-VSII

    Then unscrew the cover on the computer and replace the memcal with your new one. Screw the access cover back on and put the computer back in its place. Make sure everything is reconnected securely and then reconnect your battery (if you've got the stock radio have your pin code handy). Computer will "relearn" its settings after a few minutes of the engine running and you should be done.

    If you have any troubles (such as an error code still present) do a search on this forum as all troubles have been discussed before. i.e. For instance if you got the package from ebay you may have the wrong knock sensor.

    Good luck and let us know how you go.

    Had a request to post some pics so here they are. Knock sensor is mounted passenger side in front of the starter motor. I also took a second picture showing the routing of the loom. This location will only pit minimal stress on the pin that goes into the knock sensor (a common area of failure) and is kept well away from the hot exhaust. You can just see it peeking out from under the exhaust manifold before running through a heatshield through which another loom runs (straight arrow). It's then attached up onto the inner guard where it runs back through the firewall.

    Mark.

    Crimnl73, If you dont mind me asking, how much did the chip package cost you?

    Thanks

    i heard a rumour most chips dont use a knock sensor as they hamper performance. however the factory ones need it to run. is this true. as i think i'll wait and buy a cam/chip package instead hey.

    another dead thread dig from way back in 2005, I'm sure the OP has solved his issues and moved on.
