Keyless Entry Module Location

Does anybody know where they stuck the keyless entry module on a 2004 Taurus. Maby the 2003 and some earlear models had it in the same place. I bought a former lease car that had a credit for the module on the invoice. Im hopping that they used the same wiring harness and only left out the module. If so I can get one at the Junk yard, if I can find the connector. I did find an extra connector under the hood by the radiator. Anybody know whats that for?

Thanks
