wiring new stereo

wires go where on new stereo i have a 1995 1.6 16v sport astra

 

Hopefully your new stereo has ISO connectors? like the two light grey
ones to the left of this photo?

Your Astra should have matching ISO sockets you removed from the back
of the old radio? If not then they are probably clipped into a 'cage'
which holds the radio into the car; in which case you need to remove
the cage - it's usually only held in be a few bent metal tags round the
edge - and push the ISO sockets out of the back of the cage.

Identify which socket is for the speakers ( this will have all 8 wires
fitted) and which is for power ( this will probably not have all 8
wires fitted). Now life gets slightly complicated, as Vx use a
different pin-out on the power connector to most people. You will need
to swap the switched and unswitched live feeds over, or alternatively
there's probably a maplin / halfords adaptor lead available if you
don't fancy DIY.

hope that makes some sense...

 

Just to add to this, I recently swapped over my 1998 Corsa Blaupunkt
radio: CAR300. - The cage might be the same as mine, in which case you
need to remove a holding nut at the very back. Fiddly, as is the
unclicking of any ISO connection that may be there, plus the attenna
plug, also clicked in to the cage.

The cage is designed to be bent, pull the top side down and bottom
side UP until it collapses, then it can easily be removed.

My Pioneer CD radio had breaks in the yellow/red power cables, so they
could easily be swapped over. Whether that's the norm, I do not know.
Doing this cures the problem of the radio not keeping settings, which
stumped me for a good long time :/

A new radio won't necessarily come with an adaptor for the antenna,
but these are only a couple of quid from a good car store. I had to
remove a plastic plate (2 screws) from the left of the dashboard, just
inside the footspace, near clutch - to reach in and plug the antenna
in.
