Since you mentioned it does not have the factory tow package, but that you do have a 4-way, I am going with the assumption that the 4-way was an aftermarket addition. To use a brake controller, you will need to adapt your current 4-way into a 7-way using the Universal Installation Kit for Trailer Brake Controller # ETBC7. The # ETBC7 kit will provide you with everything that you need to adapt the 4-way into a functioning 7-way to use a brake controller.

The brake controller that I recommend is the Tekonsha Prodigy P3 Trailer Brake Controller # 90195. This controller is a proportional controller, has a limited lifetime warranty and is one of the most reliable controllers on the market. It also features an easy-to-read LCD display. You can use the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 3035-P to connect the P3 to the port under your dash, one end will connect to the port and the other will plug into the P3.

In regards to transmission coolers, the best option for your 2000 Ford Expedition with a 5.4L is that you want the largest cooler that you can get to fit, because you cannot over-cool fluids. So you are going to want to measure at the installation location on your Expedition (see accompanying diagram) and select the largest cooler that fits.

Your options are:

- Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504: 11" wide x 12" tall x 7/8" deep
- Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13502: 11" wide x 7-1/4" tall x 7/8" deep
- Derale Series 9000 Plate-Fin Transmission Cooler Kit # D13611: 11" wide x 3-7/8" tall x 1-1/4" deep

Which ever of those options are used, you will need the Derale Radiator Adapter Fittings for Ford # D13025 for installation.
