I was hoping for the RIV pinouts so that I can see if a short is required for switching between the injector line transducer or RIV pickup.

I got the AVL 823 (branded LUCAS in the UK) for a song, about 65$ and after a clean it was like new. I have contacted AVL, to get the manuals but they are not very helpful with obsolete (their words not mine!) equipment and I don't need a proper RIV as such!

Thanks so far, and what is the best way to get the manuals copies to you?
