Bongo Fury

Hi all,

I've installed a rear-view/reversing camera and monitor, all working fine when powered from lighter socket. Now I want to wire it in 'permanently' to go on when the ignition is switched on.
I'm not an auto-electrician, but I'm reasonably handy with circuits, solder etc. I just can't read wiring diagrams for some reason!
I think I've identified the switched power feed into the fuse box (top of F7, red/black chunky wire), but I'm a little puzzled about the internals of the fuse box.
The fuses only seem to have one wire 'attached' - does this mean that the incoming wire is going to a power 'bus' that feeds the other side of the fuses. If so, is there a piccy of the internal bus structure of the fuse box.
A quick poke seems to show that F1-F5 and F6-F8 are on seperate busses - the first being permanently on and the second switched. Is this correct?
If this is correct, can I just connect a fused wire to the bus-side of, say F8 (which is empty) - I would rather do this than splice into one of the other wires.
For my leisure battery, I took a big (fused) wire into a seperate fuse box and then took my feeds off the fuse box. I'd rather like to do this for the switched power too. I presume the big, incoming wire is fused ... but at what value - I'd like to use a smaller fuse for my feed from the bus.

Slightly seperately, I noticed that the switched power 'faded' when turned off (rather than just going to 0). Is this normal? It seemed to take a long time to drop, and I haven't seen it go below 0.8V - but I may not have waited long enough. Can this cause problems with equipment?

Thanks for your time

Yes the fuses your referring too are "bussed" if you look closely at the connectors they start life all connected then there are breaks made by cutting the links.
The feeds to the Busses are fused but at much higher values either 60Amp (IG-Key)

for the Ignition switched power or 40Amps from the BTN fuse


Once the power is switched off then capacitors in the ECU will hold the voltage up for a while and will drop over time getting slower as time goes on. It won't cause problems to any equipment.

If you do intercept the higher current feeds do make sure that the cable you use can take the higher current i.e. rated at say 80 Amps otherwise you are adding a big safety risk until you get to the added fuse box.

Fantastic! All I needed in a single message ... thanks for that.

I will put an in-line fuse on the wire to my new fuse box anyway, just didn't want to use a too big one - 15amp will be fine.

Happy wintering all!
