Cheers for the reply MB,

The fuse taps came with 20 amp fuses, but I did not add them as I didn't think I needed to.

I also put the original fuse in the top slot, with the main pins/fins pointing down, should they be in the bottom slot and should I have added the 20 amp fuse as well?

The way piggybacks work is you put the original fuse in the bottom holder to make the original circuit and your new fuse in the top holder to make the wire of the piggyback live, if your not putting the original fuse in the bottom holder then the original circuit cannot go live, plus you should NOT use the 20a fuse for a dash cam! You should find out what current is drawn when the dash cam is in use and use a fuse rated at the next amp above that (if it draws 0.5a use a 1a, if it draws 1a use a 2a etc) as a fuse is there to protect the wiring, even though the piggyback is rated at 20a the wire your connecting in it might not be (defenatly in the case of a dash cam, phone charger etc) this is a problem I see with the picture of the fuse box, i cannot see any fuses in the wires pushed under the fuses, if the wires are lower current than the fuses and something goes wrong with the box and it draws more current than the wires can handle but less than the fuse rating then the wiring will melt and maybe set fire, plus the fact if the unit does go short then the vehicles fuse will blow and take out the circuit on the car (hope the fuses are not for a safety feature!)  this scares me as it was supposed to be a professional installation!!!!

Thank you for your help and advice.

This was not done by a professional installer, it was done myself and when I ran into an issue i asked for help :-)

Cheers for confirming how to use the fuse taps, looking on the web at other installations some people don't add the extra fuses, but have gone and got some 2 amp fuses and put them at the top and the original ones at the bottom :-)

All plugged in now and working fine, once I figured out I need to re-thread the cameras power cable via the coin slot.

More pictures on the below URLs so completion..  :laugh:

Now onto fitting the rear camera.

Thanks

Glad you got it sorted and glad you put the right fuses in
I was commenting on the first reply you got about the professional installation 😉

Oh the only other thing is you should make sure the piggyback is in the right way round, it shouldn't really matter if your fuse is smaller than the original fuse unless your using a lot of current
