Default AC Fan and the Stock ECU

Hello All,

My '95 had a leak in the refrigerant system and I got tired of charging it. I mean hey, it is a convertible. If I am going to have a compressor under the hood it will be attached to a turbine. I proceeded to remove all of the air conditioning system minus the passengers side fan and light up button on the HVAC controls. For right now I would like to have the fan functionality remain the same as if the stock AC system was there and functional. For example: I turn the blower fan on, hit the AC button and the auxiliary fan starts up just like it would normally. (Only there is no compressor running, no coolant pressure switch, and no thermo switch.)

What do I need to do to make the ECU think that everything is there and trigger the fan relay? I have messed around with it a little, but nothing I have tried is working.
