Can a Junction Box be Used for 4-Way Flat Trailer Connector
Question:
All of the junction boxes I see are for 7 pin trailers. Can a seven pin junction box be used for a 4 pin trailer?

You could technically use a junction box like part # 3375601101 for a 4-Way connection, like part # HM38134, but since junction boxes are designed for 7-Way connections you'll need to find a way to plug up the larger hole since you're only going to be running 4 wires through it instead of all 7.
We do carry some different style 4-Way connectors like the Quick Fix # HMC20031 which make connecting the wiring a little quicker but I feel like this isn't as solid or secured of a connection as it would be using a junction box or butt connectors # DW05744-5.
