If you haven’t seen it before, you’ll probably be astonished after seeing its size. The purpose of this trailer is to attach it with a trailer for casing the wires.

Any vehicle towing a trailer requires trailer connector wiring to safely connect the taillights, turn signals, brake lights and other necessary electrical systems.

You’ll probably need a special wire, which has 7 wires inside it. The connector comes in closed form. You’ll have to unscrew it to separate the two parts.

HOW TO CONNECT A 7-WAY TRAILER CONNECTOR:

Connecting a 7-way trailer connector is definitely not easy and can be an intimidating component of your towing setup. But it doesn’t have to be if you know the complete procedure and the right technique following the steps of this guide.

Step 1 

The first step is to remove the insulation. You’ll have to strip off the solid black insulation. So, get a good quality cutter or stripper for this purpose.

Step 2  

Now put the rubber grommet through the wire. It might not fit as it is, so you might have to strip one part of it.

Step 3 - 

Strip all the seven internal wires a little.

Step 4 - 

Now pull the connector over the housing. To connect the wires, you must know the meaning of the wire colors and the connector ports. Each color of the wire has a different meaning:

  • GD (Ground) = White
  • EB (Electric break) = Blue
  • TM (Tail Light) = Green
  • RT (Right Turn) = Brown
  • LT (Left turn) = Red
  • BU (backup) = Yellow
  • 12V (12 Volt) = Black

* Are you not sure exactly what each wire does? The easiest way to figure it out is to use acircuit tester to confirm the function of each wire.

Step 5 -

Unscrew the connector, put the wires in, and screw it back.

Step 6 - 

Put the outer casing back in place.

Step 7- 

You might need to attach the Hopkins trailer connector somewhere to the trailer. You might need a changeover for that. Choose the appropriate position and mount the Hopkins Trailer connector over it.
