If I understand your query correctly Craig the answer is removing the four individual pins from the Econoseal connector. The four wires with attached pins can then be carefully passed though the hollow headlamp mountings.
Whether male or female the pins click into place on the main body of connector and can be released with the use of a narrow blade tool. Such are available as a bunch to suit variety of similar connectors. I managed with a narrow blade instrument screwdriver though.
Once cables are re-routed to new location they can be clicked back into main body of connector and waterproof plugs pushed back into place. There are YouTube videos illustrating what's involved.
