though mine doesn't have the funky dash and air con above and below it. Anyway I did some reading and was told that it would have a set of aux cables by the Handbrake and gear stick. so I poked around and sure enough found a loose connector.

however when I looked closer and peered around the net some more I became less convinced it was the right cable. For starters the colours on it were very odd, and didn't match anything I'd seen mentioned here or elsewhere.

if you can't easily make out the colours they are

pastel blue
white
brown
pastel green
white black

so I'm confused as to where to go next. is this right, am I even on the right lines. Is it even possible? Sorry if I sound a touch helpless, not really sure where else to turn.

No, that connector is not for the AUX jack, and that particular head unit does not support a direct plug in AUX jack.

So is there no way for me to get an aux input (3.5mm stereo jack) for that HU?

You may be able to find an aftermarket AUX adapter that works with your radio.

Possibly something like this:

Calling CTSCOTT for help!

i have a 2007 LB 5 speed and it came with a factory 4 pin aux connector

i check the connection on the HU and the cables that to the aux port

connection is sold, cables all work using a ohm meter..

nothing is working....

you keep stating that LB has a 8 pin set up and sedans have the 4 pin??

please help

According to the service manual, only Sedans used the 4 pin jack, but considering that only 4 pins are used, it really doesn't matter.

Check out the post below, as I suspect the switching mechanism within your port may be damaged:

the aux port looks to be in good

pin 3 and 4 is getting 2.6 ohm when a cable is plugged in

radio is model 11807

2.6 or 2.6K ?

I believe that jack is a Scion one, as the Yaris one has small text that is perpendicular, rather than parallel to the flap.

This the part number i got form the part 86190-52010 will check the car after work

Ah, that part number is definitely the Scion one, but as long as the pinout is the same and the switched pin has a ~2.2K resistor, it would work.

Can you snap a pic of which head unit you have as well?

here they are

Actually that's OK. I was able to verify by the model number that it is an AUX capable head unit. Did you verify the resistance as ohms or kohms?

2.666 k ohms is what i am reading off the aux port pin 4 and 3

with a mini jack plugged in with out the actual port plug in to the wiring harness

Grab a 2.2k resistor from Radio Shack and try a quick test:

With the 4 pin connector to the jack the wire order should be green, red, grey, red.

Take the 2.2K resistor and stick it into the red (opposite the green) and the grey and then press the aux button on the radio and see if it goes into aux mode.

No luck..... 2.2k in pin 4 red and 3 Greg

If the jack and cable came off a Scion, then the radio end may be pinned incorrectly.

The image below shows the radio connector of a Yaris, looking into the holes.

ALI: Aux Left
ARI: Aux Right
ASGN: Ground
AUXI: Switch input to enable aux mode.



Make sure that the red and black (or grey) above go to AUXI for the Red and ASGN for the black or grey wire.

Everything is correct on my end according to your schematic but no dice

I got it

Radio 11807

Is a 8 pin set up

In just added a 2.2k resistor to pin 19 and 18

But 18 pin is empty so I found random pin that fit the socket and made the connection with the radio

Everything works now

Thanks a bunch
