Which wires are for rear speakers??

[miiser]

Hi,

I want to know which of these wires are meant to be for the rear speakers.
My car it’s a hb 2009 yaris with 4 doors, but from factory didn’t came with rear speakers, so there are no wires inside the door. However I saw somewhere that the wires for them, are in the panel behind the driver-passenger seatbelt and they end there. In the picture there are all these wires that are meant to go inside the rear door but only 2 (the red and the pink one) goes inside the tube and into the rear door, so I assume these are for the rear electrical locks (manual rear windows).
So the red and the green wires (that they are more fat than the others, the light blue, and the thin red and white wires doesn’t seem to do anything there. So 2 of them must be the rear speaker harness right?? But which 2??

(Keep in mind that neither of these wires are for the seatbelt mechanism. These wires are yellow and they end further down)

I don't recall the outcomes of the numerous threads talking about rear speakers and wiring for those cars not equipped with them.

My question to you is; have you removed the bench side plastic panels to see if the are any visible unconnected wires behind them?

I have searched these threads but I didn’t find any answer and since I took pictures I decided to make a new thread to find the question once for all.
I have removed the plastics as I shown in the pictures plus I have removed the rear door panels and there are no unconnected wires either
7 wires are making their way to their rear doors but only 2 wires end up inside them. And I assume these are for the power lock mechanism.

When I was playing around (for my Yaris 2007 hatchback) with that I found out the colors below:

Left Rear Speaker Positive Wire (+): Black
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Red
Right Rear Speaker Negative Wire (-): White

Those two thin ones, white in the very bottom and red right above it.

The question is how to get them through to the door, because they end here, unfortunately.

Mmm are you sure that these are the wires ?
I assume you are correct because they are the thinnest. And I don’t think that such a thin wire can be used in anything else.

I did not try them. But I have disassembled the dashboard, found the wires plugged into the radio and according to the specs for the radio these wires are really the ones. I have cross-checked it with another piece of documentation I found and it really matches. :smile:

There's a couple options, you could get a new or used door wire harness that includes the wiring for the speaker from the dealer or a junkyard. Another option would be to re-pin the door wire harness connector at the B pillar (the other side of the connector shown in your photo) to add the two wires running to the door speaker. You can usually buy the pins with a short piece of wire attached at the dealer, or reuse them from an old connector. Re-pinning a connector is a bit more involved so you might want to read up on it or watch a couple videos before you try it. A final option would be to splice into the speaker wires at the B pillar, bypass the connector and run the two wires into the door beside the factory wiring. Either way you do it you will have to take the door panel off, unplug the connector in the photo and fish some wires though the rubber boot to the door.

Obviously the two of us are trying to figure out the same thing. :biggrin:

I have given up my chances of tweaking the current wiring between the door and body.
I would probably drill a new hole through the body and the door, fit it with some soft, squeezable rubber hose, cut the wires from the connector, solder some additional connector and put extra wires through.

Currently I am looking for that rubber hose. :)
