I'm currently (excuse the pun) struggling to wire in my 2004 Doblo towbar single socket, but no luck so far, can I just scotch lock the wires into one side of that big plug? Not sure which wire is which-no pink one on my loom...
You can scotch the wires in but you'll have to run a wire to the other side for the indicator.
If you are unsure which wire is which, you'll have to release the light cluster and trace each track back to the plug.
