Upgrading the model 2007 radio to the 7000 Series
I had
been having intermittent problems with the CD multichanger a few months after
buying the Scorpio and had tried all the tips I had found on the Forum. I even
got to a point where I suspected the fault was caused by temperature or humidity
as the CD only seemed to work after the car had been standing in the sun!
Eventually I got so fed up that I started to find a replacement. After losing a
bid on a 5000 series radio and multiplayer I had found on E-Bay, another
‘E-Bayer’ contacted me stating he was just about to place a 7000 series radio
and multichanger up for bid and was I interested - of course I was!
As it turned out the ‘E-Bayer’ was another ‘Scorpion’ who regularly contributes
to the Forum and mailing list, enter Oliver D!
“I must warn you it’s not an easy job” was the warning Oliver gave me. So I set
about trawling the main site for any information regarding the radio. Peter
Barnes’ write up of his experience was great – at least I knew it would fit.
“But that was about the 2006 without the amplifier – has yours got the amp
fitted? If so, it’s still possible but a bit more tricky getting to the amp”
warned Oliver. After 5 minutes deliberation I confirmed the sale!
The parcel duly arrived containing the radio, multichanger, cable and a RIM
(remote interface module) and so I set about planning the upgrade!
As Christmas was looming I decided not to carry out to much electrical work as I
needed the car to be working over the holiday, so the first thing was to remove
the old CD changer and the cable as the 7000 series uses different connections
at the radio end.
The changer came out with no trouble (having done this operation many times
during the quest to repair it!) but the cable was another matter!
The idea was to take the old cable out and replace it with the new. The cable
runs from the multichanger up and over the wheel arch back down and under the
rear seat into the plastic trim of the passenger side floor pan and then up the
pillar in the front passenger foot well where it disappears into the darkness of
the dash board.

At this point the removal of the glove box is required,
this again is simple, by easing off the clips on the hinges on both sides of the
glove box and then dropping it down and out!
Fitting the new cable was straightforward – using the same
route the old cable took and feeding it up and over the glove box compartment
and into the space behind the radio.
So the changer and cable was in and with Christmas out of the way I could start
on the radio!
Firstly I wanted to find the connector I needed to access on the amplifier –
enter ‘Save the Night’ Bill (or STN as he is also known as!) His first words
were “It isn’t easy” but at least he gave me the information I needed.
At this point I disconnected the 2007 radio and realized that the aerial socket
is different to the 7000, luckily my local motor factors had an adaptor
(Standard to ISO) so that was okay. Next was the power connector – they are both
the same so again no problem.

All that was left on the radio connections was the speaker
connector which as STN had pointed out was totally different – this time
Halfords came up trumps with one of their range of connectors (PC3-202) was what
I needed!
Using the new connector, for the radio end, I spliced on about 2.5 foot of cable
to each wire using a simple soldered joint and heat shrink sleeve, this then
left me to deal with the end that goes to the connector taken out of the
amplifier.
At first I could not find the amp – I knew it was behind the glove box, but I
didn’t realize that you also require a neck that turns 180 degrees! It is
actually behind the facia nestled above the glove box and below the passenger
airbag (not fitted to my car!). To access it you need to open the flap in the
top of the glove box compartment and you should just see it towards the back of
the compartment (nearest the rear of the car!)

The connector, as STN had warned, was difficult to access
and once disconnected did not have much play due to the length of the wires. I
didn’t fancy cutting the wires due to the lack of room, so I decided to try and
make up some pins that could be inserted in the connector. Some 1.5mm wire,
solder, heat shrink and a plaster for the burned finger did the trick.

At first I could not work out the connection between the
two sockets. I knew which two wires belong to each speaker but I was unsure of
the polarity. This was finally achieved but using some reference data, which can
be found on the main site in the article ‘Radios fitted up to September 1995
manufacture’ and in my case is as follows: -
Connector from radio (C967a) Connector from Amp (C629)
Pin 1 Pin 8 Left Front +
Pin 2 Pin 7 Left Front -
Pin 3 Pin 6 Left Rear +
Pin 4 Pin 5 Left Rear -
Pin 5 Pin 4 Right Front +
Pin 6 Pin 3 Right Front -
Pin 7 Pin 2 Right Rear +
Pin 8 Pin 1 Right Rear -
Armed with this information I set about connecting the radio for a final test
before fitting. With all the speaker connections made, the aerial and power lead
connected I turned it on and entered the security code, the radio ran the normal
search for a station found one and I had music to my ears!
At this point I plugged in the CD Multichanger and again my favourite music
started to play – great all that was needed to do now was to cut the compartment
above the ashtray out and fit the unit properly.
I really wasn’t looking forward to taking a hack saw to the car, but knowing
Peter Barnes had done it gave me the assurance that it is possible. The fake
wooden surround of the ashtray and radio pulls forward just enough to allow
access with a stubby crosshead screwdriver to the two screws that holds the
compartment in place.

Once removed the piece of plastic that runs between the
compartment and radio can be cut out. I also had to file the corners of the new
compartment a bit flatter to allow the 7000 radio to slide in and out without
too much effort.
I finally reconnected the 7000 radio including the yellow RIM connector and
switched on. Again all worked fine except the CD, which now gave an error
message!
Following another post on the Forum STN came up with the suggestion to take the
remote plug out – this cured the problem but left the system without the remote
stalk working!
From then on it was a case of elimination – I tried the old 2007 radio, the
remote stalk still refused to work, so it must have been either the disconnected
amplifier connector or the old CD multichanger loom that I had cut back.
I reconnected the amplifier connector – still no joy so I had another close look
at the cable I had cut from the old CD multichanger. I found that there is a
black ground wire that feeds into the multiplug connector and another coming
back out that was connected to the shielding on the Black, screened cable in the
loom.
The quality of the join was quite poor – I can’t believe it left the factory
with such workmanship but if you are having trouble with the CD player it would
be worth checking!
|
Once I made the same connection on the tail of the old
loom I had left in the car, I connected the Yellow RIM connector switched on
entered the security code and set the CD going, so far so good – next to test
the volume – YES it worked, job done!
So thanks to "Oliver_D", "Save the Night" and Peter Barnes and anyone else who
contributed to my posts and of course the founders of both the Forum and mailing
list!
Quick Step-By-Step Instructions
| Fit new CD multichanger loom from radio compartment to
boot (if old cable is removed but cutting back ensure that a join is made
between the Black ground wire and the shielding – see picture) |

|
