2000 FOrd Mustang 3.8

Does anybody know or have a diagram of what the relays go to under the dash on a 2000 ford mustang 3.8? There are 4 relays in a small box next to the under dash fuse box and I have checked 2 different service information sites with no luck on what they are as well as forums and no one has an answer. One is suppose to go to the washer pump motor but that is all I can find.

I see windshield washer pump relay, horn relay, luggage compartment lid relay and park lamp relay.
Unfortunately with no indication as to which relay is what, but you should be able to turn on each one one at a time feel for which relay clicks.
