FORD 1998 Expedition - Manual (Page 119)

If your vehicle is equipped with
the optional heavy duty trailer tow
wiring, it is pre-wired for trailer
towing. An electrical connector is
provided under the instrument
panel for installing a
customer-supplied electric brake
controller. Another electrical
connector is provided at the hitch.
This connector provides power to
the trailer for taillamps, stop and
turn lamps, back up lamps, battery
charge, electric brakes (when a
customer provided controller is
installed) and ground. The kit
included with your vehicle
provides you with adaptors to
attach the brake controller and
convert the hitch connector for
Class I trailer usage.
