How to wire a 7-pin plug

Glenn Pooley demonstrates the wiring of a 7-pin plug.

Firstly, break open the plug, remove the inner section and loosen all the screws on each terminal. You’ll notice that they are numbered and that relates to the colours that connect to each terminal. It is best to fit the black wire first, as this is difficult to get to once you’ve screwed the others in. Then place the inner section back into the casing and snap it back up. Then to test the lights, use our electrical tester which will ensure it is all wired up properly and working.
