[Collins] Help: Collins 387C-4 and 346B-3 audio system

[Ulrich N Fierz]

Dear Collins collegues
I am not deperate yet but not very far from it either:
 
To use the audio units mentioned in my radio van (to interconnect things like Collins 618T-3 and 618M-1 etc.) I am in need of interconnection and perhaps circuit diagrams. I have the data sheets and know what they are supposed to do - but do not have the wiring information.
 
Now I have tried all kinds of sources: the regional Collins rep, the avionics maintenance outfits here, manual resellers etc. All to no avail! Now I try again this respected group of experts and kindly ask for any support someone could give me.
 
Thanks for the bandwidth and have a good week!
