Problem with trailer socket
I have a 2002 Explorer 4.0L with standard trailer socket. A week ago I busted a taillight on my trailer. Bought a new one, installed it but no lights on the taillight marker circuit. Continuity is OK on trailer. I checked the trailer socket on the Explorer with a circuit tester light and found no power on the part of the socket that connects to the taillight marker circuit in the adapter. I'm wondering if the fuse for the circuit needs to be replaced. My Haynes manual doesn't tell me where to find the fuse. It says the main fusebox under the hood has a diagram describing the circuits, but there is no such diagram on mine. Would appreciate help figuring out how to fix this problem. Thanks a lot.

on my F150, there is a picture of the fuse box in the operators book in the glove box. also on the F150 there is a fuse for the trailer and a fuse for the truck. they are not piggy backed together at the bumper. dont know if the EXP is like that or not.

on my 97 explorer the tow lights are controlled by relays in the rear quarter and have a 20A fuse up under the hood. My buddy's ranger had three fuses on the inside of the door panel (one for right turn light, one for left turn light, and one running lights). The relays for his were under the hood.
Like the diagram that Steve mentions for his F-150, in each case each was listed in the owner's manual for our respective vehicles (along with a diagram of the fuse boxes- both inside the car and under hood ones). You need to read all the fuses to make sure you are not missing one. I would download a new user's manual from https://www.fleet.ford.com/maintenan...ls/default.asp and see what they say.
Once you check all the fuses then it is time to actually check the connector on the vehicle. In my case it has always been OK, but my buddy's had been exposed to enough salt water that all the contacts inside had corroded away. We replaced it with a standard towing connector we got at Wally World.

When all else fails, read the instructions...
Thanks for suggesting I look at the owner's guide--it never occurred to me they would have so much detail but in fact it has extensive descriptions of the fuse system. I was able to find the fuse involved and verified that it had blown, as I had suspected. So all I need to do is replace it. Appreciate your assistance very much.
