Cigarette lighter and side fuse panel problems for dash cam
 
I am in the process of the installation of a dash cam c/w rear facing camera and having problems.

The unit came with a cigarette lighter plug / connection and various other bits of cabling, GPS etc. and rear camera etc.I thought so that I don’t have to look at the cigarette lighter cabling from that socket I will chop off the

Cigarette lighter and get the supply from the fuse box located by the driver’s door installed an inline fuse (see attachment), plus I did not want the cigarette lighter plug in the way.

So I found a spare live empty space and connected it up and use a dash securing bolt as my negative.

I tested for a 12v supply and found that it was O.K.

Switched the unit on and got the “welcome screen” and nothing else not even the rear camera.

To cut a long story short I dug out another cable with a cigarette lighter attachment and a “mini USB” plugged it in and it worked including the rear camera, I was able to scroll through settings etc. etc.

So the question is why does it work with the cigarette lighter plug / connection but not with the fuse panel connection.

Interesting

The supplied cig lighter plug probably had a little circuitry in it to reduce the 12V to 5.1 as supplied by USB standard. Sounds like you'll have to build it in with the lighter -> USB output, or find a wire harness that has the required circuitry. Or extract the PC board from the supplied cord and use that.
HTH,

Hi there Tom
Many thanks for your contribution
It's funny you should say that I had considered stripping out the cigarette lighter pcb and then taking 12v fuse box supply into the pcb and then onwards to the dash cam etc.
If I'm honest I was a bit scared ( not of my soldering ability ) but of doing something that on the face of it does not look correct.
But now I will just go ahead.
Once again many thanks for your contribution.
I will update the thread on completion.

This is now the finished article.
Because of the small size I could either get a small ABS box that was to small or one that was to big to fit behind the fuse box / dashboard.
The black at the end is one continuous piece and then moved to the heat shrink.
The images are as progression

Oh it's going to be fine until you get pulled over and the cop rips it out, thinking he found your stash.

Just kidding; glad I could help a little, and that you got it done so quickly!

Thanks for that but he / she will not be ripping anything out because as small as that tablet bottle is 90mm x 50mm it will not fit.
BUT I can hide all my needles in there only joking :eek:
