"My newly acquired 1989 900S ...." this is where my 30-87 jumper came from, works up to about M89 where switch interupts fan current, and not a relay signal.
1) verify you are at the rad-fan relay, and not an ac-compressor or ac-fan relay.
2) get v-ohm meter, pull rad fan-relay, verify 5 slots that oem relay engages:
30 .... 12V all the time
87 .... goes to fans
15 .... ign 12V, key on
31x? ... ground path
31t? ... goes to one of fan switch tabs
3) based on your post, this custom relay should work for now, and see if u have a bad orig relay:
buy a 30 amp spst relay from radioshack ($5)
make 3 jumpers, 16Ga, one of them a Y.
single end of Y to slot 30, other ends to a load tab and a signal tab on relay.
single jumper from 87 to the other relay load tab.
single jumper from the 31? slot (one to the fan switch) to the other signal tab on relay.
