Title: 12v feed in fuse box.
Post by: Munzz on February 15, 2015, 06:18:22 pm
Hi All,

I'm looking at hard wiring my dash cam via the method in the link below.

http://www.mk5golfgti.co.uk/forum/index.php/topic,87776.msg893190.html

Can anyone advise if this is still the preferred method and/or the necessary wiring required for me to complete?

Cheers

Buy a fuse tap. Easy

What kit do I need for this?

Loads of bits on eBay but confused with the pieces I need. preferably something which doesn't need soldering.

The piggyback fuse holder is the easiest way of connecting a wire to the fusebox. If your dash cam power lead has a cigarette lighter plug on the end then the socket I used works well, but if you're not worried about the plug then you can cut it off and connect it straight to the piggy back fuse holder.

No soldering involved just crimping a couple of wires.

The dash cam is powered by the usual 12v plug, could you link me to the parts required if possible?

Thanks for your help!

I'll be fitting (Hard Wiring) a FineVU CR-500HD in to my GTI in the next week or so.

I'm an Aircraft Electrician by trade and used to be a Car Mechanic....so will do a complete "How To" guide to pluming it in (Generic Electrical stuff and cable routing), hopefully this will help a few people out.

Regards
Phil

This is the type of piggyback fuse holder I used, you want a mini blade:

This is the type of cigarette lighter socket I used:

You may be able to get the parts cheaper elsewhere. Doing it this way all you are doing is putting a 12v power socket right next to the fuse box. It's all much easier to do than it looks.

Fantastic, that would be great to see. Thanks Phil.

Brilliant; although how do I go about the crocodile clips?

Cut the black clip off and crimp an eyelet on to the end of the wire and connect this to an earthing point. There's a screw right near the fusebox.

Cut the red clip off and crimp this to the through crimp that's on the end of the wire connected to the piggyback fuse holder.

Which fuse did you use to tap into?

I just put a spade connector on a bit of wire and plugged it into a fuse holder that was on an ignition live?

I am looking to do this as well. Got the fuse tap and fuses and 12v socket etc. Just wondering, can I plug this in to an unused sport in the fuse box or will it have to go where an existing fuse is? I know if it is used with an existing fuse the original fuse will have to go in it as well but I have read that some people just use the fuse tap to wire up stuff to unused sockets in their fuse boxes that were for optional stuff or extra their cars don't have so are not connected to anything.

if your dash cam uses a standard mini or micro USB plug into the actual camera you can bypass a lighter socket all together you just need to figure out what voltage your camera runs off  e.g  my nextbase one runs off a 5v Micro USB  so i bought this

same method  live to the piggy back holder and earth to the chassis

Which fuse did you use to tap into?

The fuse way I used in the photo when I did the install was spare but was connected to the switched supply. I can't give you a fuse way number as I no longer have the car.

Have a look at any spare ways in the fusebox and see if you can see the metal connector on one side, if so put a meter on it and see if it's live all the time or when the ignition is switched on.

See this link for an explanation of how to add a circuit to the fuse box.
As already mentioned, you will need a multimeter to test for voltage on the available B+ terminals to see which are constant live and which are switched on ignition.

Remember there are different physical sizes of blade fuses in the fuse box, and make sure you fit the correct amp fuse to cover the circuit you're adding.
