Since the modules appear to be hard to find these days (at least nos anyway), I wonder if the 90-93 wiring for fluid levels could be adapted to the earlier years?The 90-93 cars do not use a fluid module.
Light blue wire is output wire to the cluster to trigger the light.
Red/yellow is 12v feed from fuse 18
Black goes to ground.
The two prongs on the end of the sensor relief on the conductivity of the coolant mix to make the connection. If the sensor was dry, no condition was made and the light would trigger on. If you manually touch the two prongs with a metal wire and the light does it go off, it’s a bad sensor
Thanks Mike, I checked red/yellow wire for power, it was good. Checked ground( black wire) ,it was good, so the brand new sensor was crap.The 90-93 cars do not use a fluid module.

So you did get theI've said it before this is the best place for real useful info.

Thanks, looking forward to any options.I’d have to study the wiring diagrams a bit, but I think it could be done. Would need to rewire some stuff though
