Need Help With a Relay Problem

So, this swap that I'm doing is 99% done, but I've got one little bug to figure out.

With the stock '98 Corolla cooling system, the cooling fan is controlled by a temp switch. With the '03 Matrix, the ECU actually controls it. I've got the wires hooked up correctly and everything, but as soon as I turn the key to "On", the fan starts running. Took me a minute to figure out, but I realized that the relay is a normally closed relay, whereas the the Matrix computer hooks up to a normally open relay. So, basically I need to find a relay that's normally open and will plug into the socket for the #1 fan relay. I checked out the one on the Matrix but the pins are totally different.

Any suggestions?

You can use a SPST or SPDT relay (automotive).

Both of them are NO (normally open) from pin 87 to 30.

I don't know if the relay will plug right into the socket or not.
