Haven't spent much time on the E32 or E34 lately, but today I got out in the garage and made some space and got up some shelfes which cleared precious floor and work space.
At the same time I did a quick tour of my E32 and noted down part numbers for various relays and modules. 
Mostly this is just for my own reference;
