Since this forum is so quiet at the moment.
Here is a new addition to my car.

I had one of these sockets on the rear bumper of my mk2 mx5. So after using my new battery maintainer
clamped directly to the battery with the bonnet slightly open, I decided to do the same installation on
this car. On the previous car I had first used a 12volt Power-In plug and socket as used on CCTV camera
leads etc. but the socket mounted on the bumper didn't last long due to corrosion. So I replaced them
with a gold plated plug and socket as used on audio + video leads.
So I fitted a gold plated bulkhead mounting socket near the bottom edge of the bumper cover and a gold
plated plug on the charger cable. Then I discovered that if I pulled the plug without supporting the
socket the plastic of the bumper would flex quite worryingly, so I added a supporting wire from the
exhaust heat shield.

I added a little plastic cap to keep the weather and road dirt out while out driving.
The yellow positive wire and the black negative were taken up through the grommet of the reversing
light cable and the black one earthed at a shield mounting bolt.

I took the yellow wire forward to the fuse box in the passenger foot-well and soldered it to one end
of a 10amp fuse plugged into an always live spare fuse socket. So no need to find a way through the
bulkhead to get to the battery.

I still always unplug the cable and fit the protective plug before driving out of the garage, but if I was
to forget there would be no damage done. To get a tight fitting cap for the socket I used a piece of
tubing sealed at one end with a glue gun and tethered with a piece of fishing line going in through the
mounting hole.
