MR2 Roadster Owners Club

Brilliant.  I've been waiting for someone to be brave enough to do this on a facelift, so thanks for posting the info.  s:D :D s:D  
I'll have to see if I'm supple enough to get myself behind the unit to see the wires in situ - not getting any younger you know!  Good idea to get a second switch, though if I can't get one I'll use the window disable one as other have.

Had a great guy over today to do some wiring work on my motorcaravan, so I asked him if he could sort out my aerial for me now that I know the correct wire to cut!  He tested the black wire & proved it was the correct one.  Then cut it and fitted a rocker switch for me so I didn't have to worry about molesting the window disable switch.  I must admit I'm very pleased with the result which I think fits in very well with the factory switches.  s:D :D s:D  (http://i228.photobucket.com/albums/ee147/Kenworj1/DSC03537.jpg)
I can now blast along with the roof down listening to CD's without the wind whistling through the aerial.

Thanks Russ - don't know what happened there!

Wow... That looks fantastic! I want one of those. Knowing nothing of wiring etc, how would you wire that up? Any pointers?

Braver than me James!

Any chance you could take a pic of the wires behind the dash indicating which one?
Hope you and Paul are well  s:) :) s:)

Just got my window disable switch (without the backing plate) Hoping to get this job done at the weekend.  s:D :D s:D

Well I would if I could find some 5amp cable....now where did I put it?

All done

I have now lost my coin holder  s:cry: :cry: s:cry:  

But I can now keep my aerial down.   s:D :D s:D  

BTW my facelift 56 plate was a blue wire not black. So it looks like it can be either colour  post facelift.

Well pleased.  Been meaning to do this little mod for ages. I wish I had done it before going to Italy when I nearly lost the aerial getting out of a very tight garage space.

Installed a rocker switch with LED today like in the pic for my aerial, hardest part was getting myself in the drivers side footwell to get to the radio cables but got there in the end then out for a spin round the lakes in the lovely sunshine and aerial tucked away.

Mark.

Yeah black wire on the plug nearest the drivers side, it's a bit fiddly but can be done without taking the radio out

Could I check that the black wire was on the connector closest to the drivers legs and was on the 3rd pin from the right on the bottom row of this connector looking at it from behind the strereo?

It was a thick black wire, similar to the main red feed wires in the same connector?

The other options are thinner blue & white wires

Thanks for the help

Yeah that is right as per the diagram in my post below

http://www.mr2roc.org/phpBB3/viewtopic.php?f=31&t=34988

It might be handy if this was put in the reference section for future use.

Just been looking at your diagram  actually! Thought it was connector C that was closest to the drivers leg? Or Have I just misunderstood

The diagram is looking at the back of the stereo so connector c will be next to the drivers leg

Just so I understand this please confirm that it's the black wire attached to pin 8 on connector C that needs to be cut??
plan to do the wiring for the mod tomorrow, have already fitted the switch (exactly as photo above) complete with wiring, which just needs connecting at the radio end now!

No it is the black wire on connector B.

Just to clarify. The stereo you have fitted to your car may only have connector A and B hence why it is the closest connector to the drivers leg.

Many thanks - can confirm that I have a 2004 Facelift with Mr T standard stereo head and 6 CD multichanger - and will definitely go for the black wire in the connector closest to the divers leg - at least that is the most accessible one!!!

Cheers. will report post "operation" and try and get some pics - although space is tight, my camera might just be good enough!

Job done!  s:bounce: :bounce: s:bounce:  
In between the showers I managed to connect the wiring to my switch for the aerial control mod. Not too difficult at all really - even had room to make crimp connections on both wires, was going to try soldering but didn't fancy burning myself (or any plastics) in the restricted space!
It was just as described - the black wire in the biggest connector, the one nearest the divers leg (that's on my 2004 Facelift standard Mr T stereo complete with remote 6 CD autochanger).

Many thanks for the advice and support.

Have taken a few of photos....
This is the connector

.....and, during a drive to prove I could run round listening to CDs without the aerial mast extended, I discovered that the radio works absolutely fine with the aerial retracted, at least in reasonable signal areas, so that's a bonus!...... CD and radio with out the mast extended!:D

You could be one of the lucky ones and be in almost line of sight or a major transmitter. Like Rowridge on the IOW, it's 400 foot high and built on a 500 foot hill. (approx)
Where I live, I am between transmitters and even with a decent antenna on my car, the average radio broadcast drops out occasionally.

So..... tomorrows job will be doing this much needed Mod!   Just hoping they used the black cable in mine   s:? :? s:?    So all i need is a rocker switch from halfrauds- which only has 2 wires and some connectors which i have in the garage.  and cut connect and mount the switch.  I hope its this easy  :-) :-) :-)     I like the idea of using the coin holder space but haven't inspected yet, Will i need a blank to drill or will a different type rocker fit straight in?

Ive got all the switches. £15 incl pnp each. Just adapt. Perfect fit.  s:) :) s:)

Cheers, But was hoping to get it done today....  Don't know if the trip to halfords is gonna be a wasted trip or not,  thats if i ever do make it out for a tinker 2day!   :-) :-) :-)

Evening all, just done this mod and thought I would share my findings, as wire colours are different again!

Red = 12v live
Red/black = 12v ignition
Black = ground
Purple = aerial
Brown = illumination
Green & green/White = speaker
Orange & orange/White = speaker

The purple aerial wire is on the bottom row of pins 3rd pin from the left looking at the back of the plug(pins facing away from you)

This was done on my 2005 red edition with Toyota 58806 radio/cd/navigation unit.

Hope this helps someone in the future

Pics please and ID number of the HU.
It would be good to know as reg date and manufacturing date can be misleading though 2005 should be clear of those problems.
It will help others who read this thread in the future.

Finally got my aerial switch mod done this evening, and i connected to black wire on my 2006, phew luckily the right one  :-) :-) :-)     No more ugly aerial and wind noise!

Thanks Dtp for the advise  :-) :-) :-)

Many thanks dtp for this thread.  The aerial being up all the time was annoying me and I was considering swapping it for a stubby.  I read this, did it this afternoon (2004 car, black wire) and now I can control my aerial.  Brilliant!

I'm pretty much an amateur at this sort of thing too, but it was pretty simple to follow the instructions in the thread, if a bit of a pain due to the tight space.

Thanks again!

So, I just:

Cut the blue/white wire,
cut the orange wire,
cut the black wire,
cut the blue wire
or cut the purple wire.

Simples, ha ha!

Can anyone tell me for sure what wire I can cut amongst this lot? My car is a 2001 with the Sony WX-C570R stereo.

Thanks.

I cut into the Blue wire on my iso loom. This way A) I am not cutting into the cars wiring. B) it's clearly labelled 'Antenna'  s:D :D s:D

That's the ISO loom there, I believe. Where was it marked 'Antenna'?

Quote from: "insx"That's the ISO loom there, I believe. Where was it marked 'Antenna'?

Yep ISO,  it says across the actual wire if you look closely. It's a blue iirc, could be blue with a white trace.

Hmm. I couldn't see anything so I struggled for 10 minutes to actually get the loom out and having checked it carefully, the only wire that has anything printed on it is the orange one which says "ILLUMINATION" and there is a blue one not connected to anything with a label saying "ATT". I can't find a definitive diagram for the 16 pin ISO connector anywhere.

There is sometimes a blue as remote to the amp, and the blue for the Leccy aerial should be in the plug. Let me see if I can find as pic for you.

Here you go..

Snip the blue wire, I put a male and female bullet connector in the two ends then from the switch wires again male and female bullet connectors. This way if you ever want to put it back to original configuration or use your stereo to ISO in another car u can just connect the bullets. Make sense?

Here is a pic to show u how the word antenna is printed on the wire. (I don't  think it's a Toyota loom but u get the picture)

OK, I found a Sony WX-C570R manual that also says it's the blue wire so I'm going for that. Wish me luck  s:) :) s:)

... Yes, solid blue seems to have done it.
