Hi all,

I was thinking of hard wiring my phone in to the dash so that I don't have to have wires all over the car when charging, and to free up the 12v socket for other things.

However, I don't know a great deal about electrics!

I've found a kit that provides a harness with the phone usb connection followed by a transformer to convert the 12v feed in to a 5v 1amp feed and then an in line fuse holder.

So I think that takes care of everything I need, just leaving me with a positive and negative wire to splice in to the car somewhere.

First question would be, have I overlooked anything so far?

Then second question is where can I splice in to?

The 12v socket is inside the arm rest on my car, so that's out. Someone suggested that I could I use the hazard light switch because that is near by and always live. But then I thought, if I splice the positive and negative on the switch, wouldn't I be creating a new circuit bypassing the switch and causing the hazards to go mental?

So if anyone can offer me any help with this, that would be great. I'm not going to do it unless I'm confident that I completely understand everything involved.

Thanks guys

Regarding the hazard switch if you splice the postive feed running to the hazard switch then the hazard light circuit after the switch will remain unchanged and will still require pushing of the switch to activate!

Hi,

Thanks for the reply. If I do that, where do I put the negative from my phone?

In assumed if I spliced the positive on the hazards, then the negative would go to the negative from the hazards too?

Thanks

Run a second connection from the rear of the existing socket.
I can make you a piggyback connector if you like so you can run a feed wire to wherever you want the phone positioned.
If you're interested then P/M me and we'll sort out the arrangements.
Btw, no charge.

I usually use the back of the radio for both positive and negative feeds, I tend to go for the ignition controlled positive, and that way there's no chance of accidentally draining my battery if I forget to unplug something

Hi guys,

Thanks for the replies, I've been away for a few days so couldn't post on here.

I'm still undecided on this really. The radio has so many wires involved that I'd be worried about getting it wrong. Where as the power socket would be easier to wire, because it is in the arm rest it would require taking a lot more trim apart to get to it.

These are the wiring instructions:

Route the power cable from the charger unit to the power supply source in the vehicle and connect as follows: 1. Connect the White wire to a Negative Ground connection of the vehicle or the vehicle chassis. 2. Connect the Red wire to a 12/24 Volt power supply in the vehicle that is controlled by the ignition switch of the vehicle.

Any other tips or suggestions to help me on my way?

Thanks again to those who have already replied.

The easiest wire to connect to would be the ignition live wire on the back of the radio loom-

Hi,

Great reply, thanks!

A couple of questions then:

1.) I have the Sony DAB single slot CD player unit, is the wiring diagram above correct?

2.) I see the ignition live, where would I put the negative from my phone charger? Would it be the one labelled "EARTH" just to the right of the ignition live?

3.) Is it OK to use scotch lock quick splice connectors to join the wires?

Thanks again for all of the help.

As long as you have the Quadlock as in the photo then the wiring diagram will be correct.
I'd earth direct to a screw or bolt on the car chassis or panel to avoid the risk of interference on the radio and also avoid a risk of any power surges feeding back to the radio.
I use scotchlocks quite happily but some don't like them, a better way tbh is to solder or crimp them.

OK thanks, I'll start getting the bits together to do this I think.

I think I'll be able to do it, if I get stuck will you help me out if I post photos up?

Im wanting to do this and feed a USB slot into the top dash storage compartment. Did you get this sorted?

Hi,

Yes I fitted a second 12v socket behind the dash and then used a dual USB cigarette charger to run one to the top storage unit for satnav and one pops out just by the passenger heated seat switch for my phone cradle.

Its all quite easy using the 12v socket at the bottom of the console, radio comes out easily, plastic fascia feels like it will break but it wont , just go easy.

Its so much more convenient .
