Club 80-90 Forums

I found the guide in the wiki, link below I just wondered how simple the cable routing is, i.e. how do I get the cable from the back of the radio under the passenger seat?
Many thanks

Under the cab mat is the simple answer

However, if you can go to the auto factors (Motorworld etc) and get some of the red and black twin core that has another layer of plastic insulation over it, like the mains wire on a table lamp etc, in fact you could use that and it has a brown wire and a blue wire in it, on a vehicle you use the brown as earth and the blue as live. The reason I recommend this "double insulated" type of cable is because it is much less prone to chaffing through. Mind you, you will be fitting a fuse at the battery end of course

I'm planning on doing this to mine (eventually) but I have had a thought (or more a nagging doubt) that my header unit (like most these days) requires a constant power supply for preset memory etc. The switching the power source would mean the power is interrupted, albeit briefly and the settings would be lost.

I haven't experimented yet to see if residual power in the circuit would cover this but seems logical to me.

My thoughts then turned to having the radio running purely from the leisure battery and not the main at all.

I'd imagine you'd be able to wire in a capacitor to provide the residual power required?

This would be ideal.Especially if you are running a split charge system

That would be how i'd have it yes There is no split charge system i yet - it's something i'd like to do myself but i'm not very good when it comes to that sort of thing
I went to try and wore the new head unit the other day - I just ended up staring at wires

Regards putting a capacitor in line, I know the theory but I wouldnt know where to begin

In the end its probably best to fit a small 4-way fusebox wired to the leisure that you can screw close to stock fusebox. Thats what I did as I found I wanted other items at the front running from the leisure battery including a ciggy socket with a USB outlet. You only need the live (positive feed from leisure) cable as earth is common to both batteries.

Just the ticket, thats what I want to do - 12v power sockets, radio, cb etc.
