Good afternoon hive mechanical mind

 

I started trying to wire a dash cam into the front of the wifes Mk1 Octy this morning. The kit comes with a hardwire set (which i prefer) instead of a plug into ciggy lighter.

The instruction are mostly in chinese, with a google translate giving me the following:

 

Black - Ground

Red - ACC Ignition

Yellow - 12v Driver(?)

VGA plug - irrelevant as not using:

 

 

 

So, I put the red and yellow wires together into a piggyback fuse and plugged that into fuse 12 on the fuse panel (Diagnostic port power). I put the ground wire into a large ring terminal and put that on what I think is the relay panels earth as below:

 

 

And, ignition on.......

 

NOTHING HAPPENS!!!!!! ARRRRGGGHHHHHH!!!!!!!!

 

I have checked with a different camera and that's not the problem.

 

Can anyone help this simpleton why it is that I haven't got this cracked???

 

 

Most dash cams just have a live and earth so don't know the yellow wire is for as I would have thought it would have just been black and red.

I'm guessing it's a camera that doesn't have an internal battery.

 

Wiring both inputs into a switched live will mean the clock is reset every time it's powered down.

 

The yellow wire is designed to go onto a permanent 12v source, and then the switched live will tell it when to start and stop recording. 

Thanks softscoop

Can you give me any ideas where I can pick up a switched and permanant 12v feeds? In the area of the fusebox?

Run the wires and join them to the back of the radio, Earth, live on ignition and constant 12v there.

Radio fuse should be plenty still I'd say.

Can put an inline fuse to the cam as well

Looks same as mine, I wired it in behind the radio.

Black - Earth

Red - Ignition Switched Live

Yellow - Constant +12v

Couldn't tell you which wire colours as I can't remember, but a good circuit tester will see you right.

Thanks all, will give that a go! Juat had the bloody stereo out as well to fit handsfree kit!! Oh well....

I didn't think modern cars had a switched live at the back of a stereo as they get a can bus signal. I certainly havn't had any luck in the past few years when fitting after market stereos, I have always had to find an alternative

On the radio there is a switched supply it's what VAG call the "S" contact supply, it switches a 12v supply as soon as the key is in the ignition, it's the Yellow/Red wire in pin 4, the "Live" supply to the radio is the Red/White wires on pins 5 & 7

or look for a permanent live in the fuse box, something like the clock/interior light circuit and feed it from that. It will only be low current draw as it is for the keep alive memory, same as the one for keeping the stations tuned on the radio

Did you get your dashcam in ok in the end?

 

Be interested to hear how it's working.....I bought a Silent Witness a while ago, it came with a fag lighter plug. So I installed a fag lighter socket in the cubby under the dash.

 

It all worked fine.....BUT......it has totally killed my DAB radio reception. Looking round the web, it seems like this is a common problem. My DAB antenna is an internal windscreen mount, runs down the left side. I ran the dashcam wiring up the right side of the A pillar but it didn't make much difference.

 

Seems I will have to remove the original Skoda FM roof aerial and replace it with a DAB one to get over the problem.
