Okay, I got this far on my own after managing to salvage partial 
diagrams which probably could be applied to my car. Here's what I've 
gathered so far:

2	K	?
4	ST2	ISV
5	31	Gnd
6	KA	?
8	LS	Ign. coil through idle switch
11	ST1	ISV
13	T	Gnd through engine temp sensor (NTC resistor)
14	15	+12V(?) through ign. switch
15	SAS	Deceleration cutoff valve
17	1	Ign. coil

The first column is the pin number on the set of three relay plates, the 
second column is supposedly the marking on the control unit. Now I'd 
only need to know the pins K and KA - apparently they're standard for 
something, but I don't know for what :). My diagram only states they go 
to a "2-pin connector, engine compartment, right", with brown/yellow and 
green/brown wires.
