eh !!

if you connect to the battery terminal you will ALWAYS have 12v regardless of ignition switch position

you need to find a switched live really - but i have no idea where to look :)

Try the fuse box behind the kickpanel. You should be able to get a supply from there, you could also try running them separetly as to not draw to much current from one supply and lose everything if the fuse blows...

I had a nose about at the ignition switch and found these wires were disconnected!

According to an american bloke on an rx site the blue one is the accessorie switched cable.....

easy enough to check

get a multimeter ( or a 12v bulb )

connect one end to the wire - the other end to earth ( door pin etc.. )

turn ignition on thru all positions - if the bulb lights or you get +12v on the meter - then you have a switched live :)
