The fuse box location and the actual spot in the fuse box where the running light fuse is located will depend on the year, make and model of your vehicle. Assuming that you have a 2014 Dodge Ram 2500, I pulled up a copy of your owners manual online and it looks like The Power Distribution Center is located in the engine compartment near the battery. This center contains cartridge fuses, micro fuses, relays, and circuit breakers. A description of each fuse and component may be stamped on the inside cover.

The F29 is the fuse slot you need . It is for the trailer running lights circuit (Trailer Tow Parking Lights). This will be a yellow 20 amp cartridge fuse.

Double check this information with your owners manual.

I have no running lights(for trailer) 2014 ram no power at either 4 or 7 pin connector I tested it with test light and also checked the fuse 29 and fuse is good, is there a connection under the bed that could be bad or somewhere else under truck?

@Ted Honestly Ted, there are several places where the issue may be on your 2014 Ram. With the fuse for the running lights being okay it is possible one of the connections on the harness may have a bad terminal. I would start by checking the connection going into the trailer connection and following it back along the harness. You will want to use a Test Light # PTW2993 to check for power along the harness. It could be your Trailer Connector # HM40975 is bad so if you have power at the connector going into the trailer connector then you know the connector is bad.
