it seems that the actual knock detection is done outside of the factory ecu ? and then piped into the ecu for timing control sorta like a after thought during the design process
so where is the small box that listens for the signal from the knock sensor located at?
anyone know where or what it looks like or if it even exsists?

However, it does not interface with the ecu, it simply changes the voltage applied to the extra two terminals on the pickup in the distributor.

As far as I can tell the knock control unit is located behind the glove box.
What makes you think that? I'd have thought the RX would have it in the same place as the wagon, but maybe i'm wrong.

On the 83/84 is this the box in the fender well on the Left side of the car?

. Could you tell me what is this gaurd that you speak of, curious?
Sorry, "guard" translates to "fender".

hmm i thought i recalled seeing a wire in the diagram running to the ecu maybe its just a signal wire to tell the ecu its knocking and to trip a check engine light if it knocks for to long

and umm you will need to drill and tap the hole in the block for the knock sensor
and also swap the distributor over i would bet
if whats been said is how it works and it infact does control the timing directly instead of the ecu doing it on the older turbo's
personaly if i was going to the trouble of boosting a non boosted motor
i would covert over to at least some kind of injection system either stock or in my case not so stock
