Corroded Towbar electric socket.

My detachable tow bar usually won’t go in the socket after I have been down a lane, it fills up with mud. I use it fairly regularly through the summer months to tow my boat out of the water and into the boat park.

I don’t use the power socket very often, but was full of mud more than once and needed washing out then a few good coats of WD40.

If it was me I wouldn’t joint the cables at the socket, if you want a 7 pin, I would joint the cables in the back of the car, it will last longer.

The last few 7 pin sockets I looked in all had screw terminals, but 13 pin might be different.

Thanks you to everyone who has replied.
I only use the Jimny as a shopping trolly and to go to the tip. The trailer is one I picked up recently and I have rewired it with a 7 pin socket. I think this trailer is the only thing the Jimny will ever pull, (to the tip and back.)
It seems to me that the pins on the 7 pin system are more robust than the 13 pin ones. I suppose I could change the 13 socket if that was straight forward.
I have an adapter.
I am still not sure that disconnecting the socket, at the tow bar is easily possible. I don't want to damage the socket and wires at the connections and then find I will need a new wiring loom.
Thanks again for replying.

There's no reason you should require a new loom. Even when the terminals are too corroded to undo, you can cut the wires flush and lose less than 10mm of total length.

The socket will be held to the towbar by 2 or 3 screws. Remove these and it will then easily come apart to access the terminals.

However if you're not confident doing it, find a local independent towbar fitter or mechanic. They will be able to do it for you in a few minutes for beer money.
