trailer tow package
In 1997, the Trailer Towing Group (option 535) included the following:
3.73 rear axle ratio
7-Wire Trailering Harness
Class III Hitch
Heavy Duty Service Package (option 53C) which includes:
130 Amp Alternator
Heavy Duty 78 Amp Battery
Super Engine Cooling
Auxiliary Transmission Oil Cooling (w Auto Trans)<O
</O
I have a ’97 F250 Light Duty with a 5.4L and this equipment, looking inside the bumper opening is two small coolers, the larger water cooled one to the left is a trans cooler, the smaller air cooled one on the right is a power steering cooler. A factory equipped harness will have ford inscription on the plug cover.

If your truck was built with the Class III trailer towing package, this includes the 7 pin wiring harness, Class III frame-mounted hitch receiver, heavy duty shock absorbers, 72 amp hour battery, and a transmission auxillary oil cooler.
My 2002 King Ranch Lariat also came with a wiring harness for connecting a brake controller, and a couple of relays. One is titled as the Trailer Tow Battery Charge Relay, and the other as the Trailer Tow Backup Relay. Check your owners manual for the location of these relays in the under hood power distribution box.
