Hi all,

I haven't got myself a mini yet, but when I do, I would like to install a 12V socket so that I can runt my sat-nav.

I have found a guide on how to do it here:
[url]http://www.minifinity.co.uk/forum/viewtopic.php?f=207&t=77888[/url]

However, they suggest using a 42amp cable for the job. I have had a hunt online and in Halfords, and the highest amp cable I have been able to find is 27amps

I would greatly appreciate any guidance/ suggestions on this, as I don't want to out-amp the battery/ wiring when I install the socket.

Thanks, Chris

42 amps, that's crazy.

the sat nav will only pull around 1.2 to 1.8amps.

Even 27 amp for any car accessories is way over the top, just get something like 8 amp car cable and stick an inline 5 amp fuse.

42 amps is a lot and the wire rating is huge. Mpi cars have a 30amp main fuse. When the cigar lighter socket was introduced it included a heating element in the plug so needed a higher amp rating. I suggest a 10 amp in line fuse is enough for Sat Nav. I would not specify the wire rating on the Sat Nav as you may add a double socket extension and run 2 accessories later.

The wiring is completely OTT, what are they considering powering with this? The other things to consider are the socket and the fuse holder - the sockets are generally rated 10amp max and you'll find it difficult to find an inline fuse holder rated above 10amps without going to midi or maxi fuses. Consider the blade connectors on the back of the socket - they're regularly sold as 15amp connectors!:rolleyes:
I'd go with 17.5amp standard or 11amp thinwall cable and a 10amp fuse. Makes it cheaper, and easier, to install and will be to the same spec as most OEM fitments - this is more than adequate to power a sat nav, couple of phone chargers, and an MP3 player all at the same time; as I said, what else do you need?

Thanks for confirming my query. I thought 42 amps was a bit high too

Best wishes, Chris

Maybe they thought you were going to run jump cables, from the socket:D

Well don't tell anyone at minifinity that, if you're not one of the 'in crowd' you'll just get flamed for daring to disagree!

The moral is don't believe everything you read on the internet:D

I can't remember what i used for Mine, i think it was thin wall 20 amp or something cable with a 15 amp fuse. 2 amp cable will be more than fine for the illumination.

One neat thing i found was a piggy back fuse holder on ebay, it plugs into one of the fuse holders in the MPi and gives you a fused spur for the accessory as well as giving you another plug for the original fuse.

They're only listed by one seller - search for [B]ezled [/B]. If you use one just consider what's already on the fuse position, preferably something with a decent load that you don't use much.

I'd have to look to see what mine is on, i forget now!

That's the guy, at the time i tried to find some by trawling the small accessory racks in the independent car shops, but never found any.

Originally i wanted use one of the spare fuse holders in the fuse box, but i couldn't find the appropriate terminals to fit them. I think i emailed AMP at the time, but i don't think i got a reply.
