Default 91 civic lx sedan obd0 wiring harness b20b

Question ok the back of the b20 doesn't have all the sensors I need for instance there is nothing to run the fans the oil light sensor is there but I think that's it so what is everyone using to run there fans?

Run the wires from the back of the block to the thermostat housing fan switch of the B20. You are planning to convert to MPFI correct?
