Im working on a light plant which only has 4 wire. How do I hook up a 7 way round plug to this trailer?

Expert Reply:

If you have a 4-Way Flat connector on your light plant then the easiest way to connect it to the 7-Way on your tow vehicle would be with the Hopkins Adapter # 47345.

We also have the Hopkins Adapter # 30955 which you could permanently install on your tow vehicle by simply disconnecting the US Car Connector from your current 7-Way and plugging it into the back of this adapter. This would give you both a 4-Way Flat and a 7-Way Blade connector so that you don't have to keep track of an adapter.

If you have a different 4-Way on your light plant then I recommend swapping that out with a flat plug like the Hopkins Endurance Easy-Pull # HM38134 as this is the standard connector for basic trailer lighting.
