Radio Wiring Diagram Needed!

I have searched high and low for a readable version of the Radio Wiring diagram for the 2005 1200LT.

Can someone who has it send it to me at [email protected]? It would be greatly appreciated!

I have made the choice to "Jensenize" my LT. Tupperware is all off, and I am working on mounting the Commander unit to the stingray.

I am leaning on putting the amp unit into the back of the R saddlebag. My reasoning is that future access to USB or Aux inputs may be needed, and I like the prospect of putting more 'stuff' in the glove box. If I mount it on the back wall, it won't take up too much space and it will still be easily accessable if something goes wrong.

Thanks in advance!

Re: Radio Wiring Diagram Needed!

Look at CochinoSucio's thread on his radio install. He mounted it in place of the CD changer, and also put USB etc in the oddments box.

As for the diagram, I will try to see if I can find it. JZ has, IIRC, posted it not too long ago.

Re: Radio Wiring Diagram Needed!

Thanks John! However, its really tough to make out some of the coding and I would like a legend of the connectors if at all possible.

Does anyone else have another version?

Re: Radio Wiring Diagram Needed!

I will post what I have in a couple hours. That way a future search by another member will show all wire color codes and plug locations. Need to get home first.

Re: Radio Wiring Diagram Needed!

Ok, sorry for the delay. Longhorns, chickens, ducks, cats and dogs were very demanding today!

You will no longer need the intercom or the remote radio controls, so don't worry about those wires, or connectors.
Here is what does apply to you.....

Connectors under the left side of the stingray....
Red----------------------Battery CONSTANT (memory)
Brown-------------------Ground
Purple/Black Stripe--Switched, fused (15A)

Blue/Red Stripe-------Right Front +
Blue/Purple Stripe----Right Front -

Yellow/Purple Stripe--Left Front -
Yellow/Red Stripe-----Left Front +

Connectors under the passenger seat
Yellow/Blue Stripe-----Left Rear +
Yellow---------------------Left Rear -

Blue/Purple--------------Right Rear +
Blue/Grey Stripe--------Right Rear -

* The speakers have crossovers after the connectors
* You can splice the rear speakers at the front connector, however, if you are putting the main unit in the right rear saddlebag, the rear connector is much closer.
* Splice the rear speaker wires before the connector, so you can still remove the topcase without cutting any wires.
* The speedometer wire is irrelevant, since it is used for speed/volume control on the factory radio only.
* Remember, you are going to have lots of extra wires going lots of different directions. No worries. You need the basic new wires, not the rest of the rats nest.

* I would use "Western Union" solder joints, heat shrink wrapped.
* Most importantly, plan and do the best with every step. Don't cut corners and you will love the end product.

I hope this helps, let me know if you have more!

Thanks a bunch!

However, I think the wire coding is for 1999-2004. I have a 2005.

John sent me some 2005 schematics which happened to be in German. These did not seem to jive with the coding you provided above. In deciphering the color coding at the Radio connector (using the German information), I was able to come up with the following:

Red----------------------Battery (+) (30) CONSTANT (memory)
Brown-------------------Ground (-) (31)
Purple/RED Stripe---- (supposedly) Ignition (+) Switched **
WHT/PURPLE STRIPE---- "I-BUS"

Blue/Red Stripe-------Right Front +
Blue----------------------Right Front -

Yellow/RED Stripe----------Left Front +
Yellow/BROWN Stripe-----Left Front -

Yellow/BLACK Stripe-----Left Rear +
Yellow------------------------Left Rear -

Blue/Purple-----------------Right Rear +
Blue/Grey Stripe----------Right Rear -

I was able to use the Google German translator to help me determine the pinout of the main radio connector which is what I am looking to tap into.

**My only issue is with this wire. According to the German schematic, Pin #5 on the radio connector (Purple/RED Stripe) is a switched power source. However, the smaller conductor gage leads me to believe that it is a "data" type circuit, and the fact that I have no DC voltage on the conductor when I turn the IGN Key. However, #30 and #31 give me 12V constant as shown.

So, I am looking to tap into a switched ignition circuit that will power my radio. The Jenson I have does not require a constant 12V from anything. So I will cap off my #30 conductor in case I need it for something later.

Any suggestions?

Have a great weekend! I wish I was riding, but I have the steed all apart in my garage.

Pin 5 is a switched power source ( more of a signal to the radio and dash) but it comes from the radio controller not the bike so with that plug undone there will be no voltage there. You may have to run a switched lead in from else where.

Question Re: Radio Wiring Diagram Needed!

Hi all,

First of all, sorry for some bad English writing from France ...

Are you sure that Pin 5 of radio plug is an output from the radio and not from the K12 ?

I'm facing a big prob today about this, and your 2012 answer.
I did use attached wiring diagram : wiring a standard 1A USB power converter (12v to 5v) to pins 15 for ground and 5 for switched power supply.
Actually this diagram shows Pin 5 is an input ("Eingang" german speaking) for the radio.
And, I'm not really sure now (after reading your post), but when I measured each pin voltage (before connecting anything !) I remember that this one was 12v (when key switched on) even without radio connected ...
My problem is that I had correct power for a few hours, but when I wanted to have a last test before reassembling everything, I had no more switched power on this pin 5.
So I do not know at this time if my prob comes from radio or from bike ...
But you can imagine in what state my K12 is at this time as I tried all day long to find where this switched power supply signal could come from (of course 7,5A fuse already verified) ...

A few post before, Cochinosucio said that this pin could be fused (15A), but I have not any idea where this 15A fuse could be if it exists (inside radio, need to dismount) ?

I have to precise that my K12LT FL is a may 2004 one, and that the single CD radio is the only sound equipment I have at this time (it is a Becker Pro 2000 Ece 65.12-7 ...). But the attached wiring diagram seemed to match my bike one's as measured voltages.
I even did try to attache AUX inputs on Intercom plug, and it worked fine (except amplified sound) until switched power failed !

Any help would be greatly appreciated before I have to forget any idea of listening music sounds on my K12

Thanks
Thierry

Hi all,

Having not any return to my posts in this forum since two days, I have "solved" this problem with the help of some french fellows.
You can find the solution here (you will have to translate from french) :
[résolu] K12LT 2004 - Problème signal +12v "ignit" radio CD

So I am now looking for a radio controller (keyboard) without lcd display and good working of course !
Thanks !

Regards,
Thierry

Question Re: Radio Wiring Diagram Needed!

Bonjour John !

It is not exactly a French translation of your German document. Yours is fine by itself whith the help of a translator !

But, as I did not find any information anywhere else, my post is an explanation of power signals coming from / going to bike on the 6 pins plug which is on the left (the 3rd one from left side) outside the "Tupperware" box including radio and it's keyboard (see picture attached) !

Anyway, does anyone know where I could find a correct keyboard electronic card WITHOUT lcd display to replace my "faulty" one ?

My post also explains on which pin a +12V signal should be connected to be correctly protected by the 7,5A (15A for some bikes) fuse !

Re: Radio Wiring Diagram Needed!

I think this is the third plug. The middle one is the front speakers the one on the left is handle bar controls. So this one makes sense. The rear controls and rear speakers are in the barrel connector.

My electronic diagram is hard to display as a picture since you have to zoom in to red wire colors. Then you cannot see it all in one picture. Maybe these will help you.

Re: Radio Wiring Diagram Needed!

I think I have them, but they're in German. Also one or two pages may be too small to convey clearly by fax (my only way).

Also have a file on installing an aftermarket radio hooked to the stock handlebar controls.

Advise a fax number if you'd like me to send.

Re: Radio Wiring Diagram Needed!

So does pin 5 work for turning the radio on? Or do you have to run a new wire to the ignition?
