You've got them correct so far. I've added some info below. This is reading from the '86 5kqt diagram out of Bentley.
2 K (A/C control unit, +12V when A/C is operating)
4 ST2 ISV
5 31 Gnd
6 KA (radiator afterrun control unit)
8 LS Ign. coil through idle switch (ECU pin#20)
11 ST1 ISV
13 T Gnd through engine temp sensor (NTC resistor)
14 15 +12V(?) through ign. switch
15 SAS Deceleration cutoff valve (ECU pin#4)
17 1 Ign. coil
I'm not sure about your control unit. I thought they used 2 relay sockets, not 3. What type of car is it from? Take a look at... http://www.sjmautotechnik.com/injector.html#mixture
There's a bunch of good info about this ISS system.
