240Z: Details about a 240Z Rallye fuel injection “experimental” setup

Some of you more geeky readers might know that Nissan used to experiment with some electric fuel injection system in some of their works rallye cars. I’m no expert by any means, but i recently stumbled on this article of some guy who found an original set, and thought it might be interesting for some of the readers.

Here’s a photo from the very control box in the Datsun 240Z at the 1973 monte carlo rallye with the Drivers Tony Fall and Paul ester (Picture Jos van der Aart).
Note the tape on the knobs to protect the drivers from changing the settings during the race and the foam padding below the box to protect the navigators knees from hits on the edge of the box.

Update 18.04.2023:  I was able to obtain a wiring diagram of the very similar fuel injection system from an EA Safari Datsun Rallye violet 1800cc with two cylinders less.
Thanks to Sean Dezart for sharing with me, and thanks to Alan T. who may have provided it originally to Sean. Such a rare find.
It seems the setting box has one additional knob compared to the Z-box but otherwise it looks very similar from my limited understanding.
