Anyone converted from 7 pin to 11 pin towbart connector?

[opel_estate]

I have a facelift with the gm towbar connector box, and want to convert from 7 pin to 11 pin.
Other than changing the connector itself and the wire harness do i need another version of the connector box?

If you mean 13 pin, then no. All you need to do is rewire the new plug. I did the opposite, our car only came with a 13 pin option on electrics, so I changed the caravan from 12N/12S to 13 pin.

If you don't fancy doing that you can get an adaptor lead from 12N/12S to 13 pin
