Automatic Headlights

I've searched the topics for this specific topic but all I have found was information on the DRL.  I have a 1995 base model and I wish to disable the automatic headlights from turning on.  The issue I am having is in the afternoon when the headlights keep turning themselves on and off.  Its really anoying.  I found the sensor where it normally is which is under the defroster vent.  I called chevy and asked if there is a workaround or a way to disable the sensor and they tell me no.  I asked if I was to cut the wire to it if it would disable it and they said no and that the headlights would be on all the time cause it would then think it is always dark.  It must work like a solar sensor does and creates voltage when there is sunlight therefore keeping the headlights off.  If I was to cut it and splice in a power wire to the sensor to simulate voltage how much would be too much so I don't blow the system?  I also thought about getting a small light that would fit under the vent to keep light on the sensor.  Anyone have any suggestions or ideas?  I did find the box under the dash but it disables everything plus the driver side high beam like other posts say and I would like to keep the DRL active without the auto lights.

As far as I know, there aren't auto headlights, just DRLs. No darkness sensors or anything like that. I'm pretty sure 95 Chevy's are before the sensors' time. Just unhook the connector and then ground the headlight. If you want lights on during the day, turn them on yourself. If you forget, people will still be able to see you, and the car won't let you forget to turn them off.

Yes there are automatic headlights.  I found the sensor under the dash defroster vent.  I know this cause I used a flashlight to turn the lights on and off.  I don't want to disconnect the box if I don't have to cause I like how the DRL are really dim when they are on.  I am tempted to take the sensor out and see how much voltage is generated using a volt meter when it is in broad daylight.

I've heard that you can disconnect the sensor from the dash harness (there is no box that it plugs into, it's a 2 wire sensor), and install a resistor in the dash harness side to simulate using the sensor.

I have no idea what ohm to use though.

Sweet.  Should be able to determine ohm resistance by using a ohm meter with sensor in broad daylight.  I will try this.  Thanks.  

If anyone still knows other ways as well please still let me know...
