Disable "Add Coolant" light and alarm

Hi Guys, more trouble.

As some of you know, I'm making an electric RX-7. Good news is, I'm nearly done at long last. Bad news is, I'm getting an "Add Coolant" alarm when the car is on for more than a few seconds. Obviously, I don't need coolant. How can I disable this alarm?

Take the wire that goes to the Low coolant sender( at the top of the Rad) and disconnect it from the sender.
Then take the wire that went FROM the harness and connect it to ground.That will stop the buzzer from going off.

Thanks for the quick response. Can you help a noob with some of the lingo? What do you mean by the "Rad?" Could you be more specific about which wires, where I would locate them?

Rad is radiator. There was a sensor on the top of it. Disconnect the sensor and ground out the wire that runs to the harness.

Okay...since the radiator is gone, I'm pretty sure the sensor is disconnected.

The wire for it that runs to the harness then is what I need to find.

So looking through the wiring diagrams, would it be BR/W (ME) marked in red, or BR (F) marked in green that I should be running to ground? I would think the red wire, but I want to check lest I destroy something.

single wire on the front passenger side that has a bullet style connector ..that is the wire you need to ground.(attach to the car's body)..BROWN wire.

Never mind, I figured it out. Clip the BR/W wire, and ground the B wire.

I was able to disable my coolant warning by properly filling and bleeding the system. The warning never comes on.

Sorry this is a random question, but what book/manuel is that wiring diagram from?
