Volvo 740 - looms, amps and wierdness

[RichardK]

As you probably realise, a 1989 Volvo 740 isn't worth as much as a CD
changer cable, but it's still nice to have music. The battery failed and
as a result, the CR-702 radio has a code request.

I would normally just chuck it out and put another radio in, but the
wiring is strange, and primarily I'm curious about the configuration of
the speakers. The Volvo radio has a power plus some other things
connector, antenna, ground and a 6-pin DIN connector marked "AMP" (in
addition to a covered one marked "EQ").

Presumably this means the car has an amp buried in the dash somewhere?
Or is it just misleading? The connector for the main loom has 10 pins,
plus a secondary pair of wires which I think must provide power to an EQ
or similar device.

Does anyone know of an adaptor for the loom, or how to obtain the code
from the Volvo radio? I'm going to see if the dealer can provide it (a
solution I've read a few times online) but I don't hold out much hope
for a 16 year old wreck.

Otherwise, does anyone have a Volvo 740 original radio (CR702, 708 or
similar) which uses the same connection scheme of a 10-pin (of
potentially 14) main, plus six-pin amp? One with an unbroken fascia
surround would be nice. Obviously I'd need the code for it...

(The aim, incidentally, is to take the beaten up 740, which my friend
has deemed to be scrap, and make it into a respectable car for £100.
This is to include fixing a leak on the PS rack and replacing the front
wings which have mysteriously rotted away, despite the rest of the car
being surprisingly free of rust. £10 has already gone on replacing a
smashed mirror!).

It's under the driver's side dash. You need an Autoleads PC2194, which
bypasses the amp and allows you to fit a standard ISO head unit.
