Zac,
There is not much point in having it run when the engine is not running.
I use an after market fuse box such as an Ashdown or Bosch etc for my
auxiliary circuits. Its heaps tidier and easier to control whats happening.
If you want to get really smart use Din rails and slide on relays of the
fuse block.
Cheers
Feral Errol

Thanks Errol. Will that run when the car is off or is that a pointless
idea?
Tonight I started pulling apart the loom I have. I have been unthreading it
bit by bit and placing tight zip ties around it so it keeps it's
shape/form.
I intend to put this new wiring for thermo fan, high beams, O2 sensor and
anything else that is a good idea in neatly, then tape it all up again then
install! I might even put a little thermo fan on the back of my
intercooler,
provided I can get the radiator in how I intend!
I like the idea of the more fuses. I am not intending to run mega stereo or
driving lights but I want this loom to work 100% reliably. If you can
recommend a way to wire up these more suggestions while the loom is apart
(ie use a bigger fuse box, etc) could you please tell me?
Zac
