How can you tell if you have the HD Trailer Tow?

I have a 2004 Expedition, that is an ex-police cruiser. I was wondering how you can tell if it has the HD trailer tow package. The truck only has the 4 wire harness in the rear, but I wasn't sure if the police package had the heavy duty radiator and the auxiliary trans. cooler. Could anyone help me out?

HD Transmission radiator is either:

7-row full width or 11-row partial width.

Standard transmission radiator is:

5 row or 7 row partial width.

The partial width radiators appear to be the older versions, the full width starting in '07.

HD Trailer tow includes the full 7-pole wiring to the rear bumper.

Here's a bad picture of my transmission cooler. Would this be the heavy duty model?
