16 Gauge cable - enough to get from your current battery, to where your new one will go (for me 5 metres Red, 1 Metre Black)
Solenoid Battery Isolator - MY was a Chargegaurd one from Capital Instruments, about $150.
8 Way FuseBox
However many switches you want (explained later)
Enough cable to wire everything else up
The wiring diagram that I worked out for my truck is below:
Basically I wanted to have two different fusebox's one for items that don't have an off switch (switched FB) and another for ones that do (Non switched FB, ie permenantly Live)
This works well for me as I have allsorts of bits & pieces that when powered up, stay on. ie, Power for my wireless radios, Stereo Amp etc
After fitting the solenoid isolator the engine bay looks like this:
The yellow circle is the solenoid battery isolator, basically what it does is, it watch's the output voltage of the main battery and won't charge the Aux Battery until the Main is at 13.5V.
I cheated on mine and have used one fusebox for everything, the First 4 fuses are fed from the switch on the dash (Circled in Red). The last 4 are fed directly from the Live Terminal of the Auxillary Battery.
The Switch circled in yellow is for my rear work light. It's fed from a live fuse, so can be used without the other stuff turned on. (Only problem now is I have run out of blanks in my dash)
I installed the fusebox in the passenger footwell, by cutting a hole in the plastic thingy:
All the cables run from the engine bay (Passenger Side) through the existing gromet into the passenger footwell. From there they either goto the dash board (hidden behind the aircon stuff) or directly to the fusebox, or to the rear of the car under the carpet.
While I was running all the cables I ran 1 x 5 core cable to the dash, 1 x 5 core to the center console thing, where the gear lever is and finally one 5 core to the boot. This will allow me to add stuff all over the place without re-running cables. eg, one of the five core wires, is used for my rear work light:
Also as the battery box is mounted in the boot, I had to run the 16 guage cable back to there at the same time:
If I think of anything more to add... I will, Mike, hope u dont mind me making this a sticky, thought it would be useful for people
