I would use these with the appropriate Raychem pliers also available from RS. Low profile and hermetically sealed with the heatshrink sleeve that has resin at each end which melts when shrunk sealing the splice.

I have used lots of Wago on my Defender but encased it within a high IP rated enclosure.  Click image to enlarge If you go through life with your head in the sand....all people will see is an ar5e!!

Good alternative
Not available in Chile, but I can bring it from USA. Thanks for the idea. Cheers! Eduardo MY 2007 110 SW PUMA 2.4: Big Fog of 64' MY 1994 Jayco 1207 Folding camper: "El Tremendo" Click image to enlarge |

Thanks again for all the advice - so many ways to kill a cat...
My final solution was soldering with a storm lighter/mini-torch my colleague has lent me (never thought I'd be glad he smokes). As variously suggested, wires were spliced, tied around with copper strands and had a shed load of solder melted into them with a blue flame. Filed it all tidy afterwards. It actually isn't as crap as I was expecting: [URL=] Click image to enlarge[/URL] Tatra - good points all (pity I only read them after I did the job) - however, I will make sure the joint is fixed to something to prevent breakage. Mal - nice solution. You always find the obscure stuff. I was also going to encase any mechanical connection - with butyl tape (also IP-67, I suspect). Now I just have to wait for the glue-shrink to arrive off the bay :thumbsup: Admin note: this post has had its images recovered from a money grabbing photo hosting site and reinstated  Tell someone you love them today because life is short.

When you use the glue heat shrink, as it's starting to shrink and the glue is melting, slightly separate the two wires and using a pair of needle nose pliers crimp the heat-shrink between the two wires.
Leave the pliers there for about 30 seconds until the glue has set. This will give you a better waterproof joint. Again don't forget to rough up the insulation a bit with some emery cloth. |

 It's not so much 'obscure stuff' but on the 85 metre high-speed catamarans I work on with regards to environment from an electrical perspective it's probably the harshest it gets. The fact the vessels are aluminium they sweat due to rapid temperature changes, add seawater, oil etc into the mix and you can perhaps see what I mean. Through trial and error we use what is best as it saves the inevitable revisit to the same job over and over again.

Time to get tinkering then
Just a standard deffy plug (TD5, Puma?) with a 12v battery or will any plug do? Tell someone you love them today because life is short. But shout it at them in German because life is also terrifying and confusing... |

Learning something here again. Interesting comments about Wago connectors which I did not know. Would you use these in below link on a Defender for electric connections provided that there is space available? 3-way and 2-way.

You merely look after it for the next generation. http://youtu.be/yVRlSsJwD0o https://youtu.be/vmPr3oTHndg https://www.youtube.com/watch?v=_GtzTT9Pdl0 https://www.youtube.com/watch?v=ABqKPz28e6A https://www.youtube.com/watch?v=rLZ49Jce_n0 https://www.youtube.com/watch?v=XvAsz_ilQYU https://www.youtube.com/watch?v=K8tMHiX9lSw https://m.youtube.com/watch?v=dxwjPuHIV7I https://vimeo.com/201482507 https://www.youtube.com/watch?v=ZSixqL0iyHw |

These were my originally favoured mechanical alternative (i.e. first one that came up on eBay
 ).
A few things that I would take care of though: 1) are they original Wago and not cheap fakes? It seems impossible to get the real deal (e.g. Superseal) these days 
2) How much surface area of the wire is in contact with the connector? Would voltage/current etc. be a problem? 3) How easy is it to waterproof them/would they deteriorate over time e.g. due to bimetallic corrosion? 4) To deal with 3) how large/expensive would an (or multiple) IP6something enclosure(s) be? 5) How mechanically stable are they?

I wouldn't use them in an exposed environment as a permanent solution.
Have seen this sort of connector used and fail in domestic use (house wiring) so it's no from me. Andy |

To add to that: Wago has different types of these connectors, for massiv or stranded cable. Because for automotive applications you always use stranded wires, make sure you use the right type. There is a lot of info on the Wago website. I think they are very capable and usefull, if they are well installed, i.e. with good fixing of cables and connectors on a firm surface or in a proper enclosure.
