Setup of Sony MEX-BT3900U with Metra ASWC

Hi everyone!
Just have a couple of questions with my setup. Here's what I have...
* Sony MEX-BT3900U radio
* Metra ASWC (interface and wire harness)
* Metra 70-8114 wire harness
* Scosche TA2103B Mounting Kit (comes with the 6096B Aux and A/C Retention Harness)
* Scosche TA02B wire harness
* Sony XA-MC10 Microphone

Steps...
1. Connects the Metra ASWC interface to the Metra 70-8114 wire harness. Doesn't use the wire harness that comes with the Metra ASWC.
2. With the Metra 70-8114 wire harness, connect the white RCA to the Sony MEX-BT3900U left AUX
3. With the Metra 70-8114 wire harness, connect the red RCA to the Sony MEX-BT3900U right AUX
4. Connect the Sony XA-MC10 to the "mic in" female 3.5mm wire on the back of the radio unit.
5. Solder/Tape the Scosche TA02B wires to the proper colored stereo wires.

My questions are...
* With #2 above, do I connect it to FRONT left, REAR left, or BUS IN left?
* With #3 above, do I connect it to FRONT right, REAR right, or BUS IN right?
* With the 3.5mm male wire associated with the Metra 70-8114, where do I actually connect that? Into the AUX input infront of the radio unit? The only 3.5mm female wire is on the back and that will be used by the Sony XA-MC10.
* Do I need to use the "6096B Aux and A/C Retention Harness" wire harness that comes with the Scosche TA2103B Mounting Kit?
* Anything else I should know/correct?

 

Thanks for the reply, F8L! I did check your stealth installation.

If it helps to answer my questions, here are the images of what I have and the steps (related to the steps I mentioned in my first post above)...

Thanks ahead!

 

Thanks for the reply and clarification, usbseawolf2000! I guess I'll return the Sony XA-MC10 Microphone since there's no other connections for it. I'll definitely take a look at the PDF . I'll reply back if I have any other questions. Thanks again!

 

So after almost 5 hours of installation (with the help of my bro) last night, we've managed to install the radio. Radio works great but unfortunately there are two problems: 1) Red triangle on the dash and car with exclamation mark on the top of the MFD and 2) the red light of the Metra ASWC interface is not a solid red (keeps blinking with a steady pace).

Here's what I did.
1. As suggested by usbseawolf2000, I used the Aux and A/C Retention Harness. Because I used that, I didn't use the Metra 70-8114 wire harness and instead I used the wire harness that came with the Metra ASWC.
2. With the help of the Doc file attached by fastring (thread called "Install Sony DSX300BTX and Axxess ASWC Steering Wheel Control Interface"), here's how I connected the wires.
a) The GREEN/ORANGE wire of the Metra ASWC connects to the WHITE wire of the Aux and A/C Retention Harness.
b) The BLACK/GREEN wire of the Metra ASWC connects to the BLACK wire of the Aux and A/C Retention Harness.
c) Plugged the 3.5mm of the Metra ASWC on the back, bottom right of the radio unit (see attached diagram below).
d) Did not use the BROWN wire and the RCAs from the Aux and A/C Retention Harness.
e) With the RED wire of the Metra ASWC, radio, and Scosche TA02B, I connected them all together.
f) With the BLACK wire of the Metra ASWC, radio, and Scosche TA02B, I connected them all together and connected them to ground.
g) As for the remaining wires, I connected them to their corresponding colored wires. I believe I didn't use two colored wires (ORANGE and LIGHT BLUE).
h) Connected the 3.5mm of the Sony XA-MC10 Microphone to the female 3.5mm wire, located behind, top left of the radio unit.
i) Connected the antenna on the back, bottom left of the radio unit.
j) Once all of that was done, I plugged the Metra ASWC wire harness and the two Scosche TA02B wire harness to their corresponding wire harness that's connected to the car.

I'm thinking the two problems are caused either by step (e), I didn't use the BROWN wire from the Aux and A/C Retention Harness, OR I mixed up the connection of the colored wires (highly doubt it though).

Later on today, I'll try to fix the red light of the Metra ASWC interface either by holding the volume up button while the interface is blinking or tap the volume up button constantly while the interface is blinking. If that doesn't work, then I guess I need to checking the wiring.

 

Update: After turning on and off my car to drive and park my car around my area, the red triangle on the dash and car with exclamation mark on the top of the MFD disappeared!!!

 

So I tried fixing the red light of the Metra ASWC interface by holding the volume up button while the interface is blinking. That didn't work. I also tried tapping the volume up button constantly while the interface is blinking. That didn't work either.

I did try manual programming (http://www.metraonline.com/files/products/INSTASWC_web.pdf) the Metra ASWC but with no success. Finally, I looked at the Metra ASWC PDF file from axxessinterface.com to see if I used the correct wires associated with the wire harness that came with the Metra ASWC. It stated to use the Green/Orange, Black/Green, black, and red wires. All other wires on the ASWC should be taped up since they won't be used. From what I remember last night, I did just that.

If my connections seems correct after checking the wiring later tonight, I'm going to replace the wire harness that came with the Metra ASWC with the 70-8114 wire harness. From what LovingLife said in http://priuschat.com/forums/gen-iii...nics/75036-metra-axxess-aswc-interface-3.html, it worked for him perfectly. I'm assuming also that he didn't use an Aux and A/C Retention Harness. His connection might be Metra ASWC interace --- 70-8114 wire harness --- car wire harness.

 

Yeap, I can control the A/C Auto, Temp, Circulation, and rear/front defoggers from the steering wheel. Just not the volume (up/down), mode, and seek (up/down) from the steering wheel.

 

usbseawolf2000, does that mean I can indeed replace the Aux and A/C Retention Harness with the Metra 70-8114, and with the black wire of the 70-8114, ground it to the metal cage? And no worries about the misinformation... you're a great help!

 

So here's my conclusion after doing the two different wiring setup for the Metra ASWC.

Setup 1
(Metra interface --- wiring harness that came with the Metra interface --- Aux and A/C Retention Harness --- car's wiring harness)
Result: A/C Auto, Temp, Circulation, and rear/front defoggers WORK from the steering wheel and on the MFD but the volume (up/down), mode, and seek (up/down) does NOT WORK from the steering wheel.

Setup 2
(Mettra interface --- Metra 70-8114 --- car's wiring harness).
Result: Volume (up/down), mode, and seek (up/down) WORK from the steering wheel but unfortunately A/C Auto, Temp, Circulation, and rear/front defoggers does NOT WORK from the steering wheel AND climate does NOT WORK on the MFD.

So which setup did I choose? The obvious one, which is Setup 1.

I'm not really sure why the first setup doesn't work correctly considering that it worked for fastring in http://priuschat.com/forums/gen-ii-...ss-aswc-steering-wheel-control-interface.html. I looked over and over again at his Doc file and everything I did seems fine. He also had the same mounting kit (Scosche TA2103B Mounting Kit), which should have came with the same Aux and A/C Retention Harness.

As of right now, the only reasons I can think of that's causing the problem in setup 1 are 1) there's something wrong with the wires that came with the Metra ASWC interface, 2) there's something wrong with the wires of the Aux and A/C Retention Harness, or 3) there's something wrong with both set of wires.

I did email Metra for their feedback and hopefully I'll hear from them soon.

By the way, for both setups, I did ground the black wire on the metal cage, encasing the radio. Also, I did do the stealth install (thanks, F8L!)

 

I did do "ASWC red goes to radio harness red" but I grounded the black Metra ASWC wire to the metal cage for both setups. As you can see on Setup 2, the Metra interface worked fine even when the black wire was grounded to the metal cage.

I'm guessing when fastring said, "connecting remote steering wheel button wires," he meant the GREEN/ORANGE from the ASWC connected to the SCHOCE WHITE and the BLACK/GREEN from the ASWC connected to the SCHOCE BLACK.

As for the "wire from ASWC connected to Sony wire harness," I don't see any Blue-White or Blue-Yellow wire from these images...

and
http://priuschat.com/forums/attachm...0-setup-sony-mex-bt3900u-metra-aswc-metra.jpg (image on the right).

There's no Blue-White or Blue-Yellow wire also from the Metra 70-8114 (image on the left of http://priuschat.com/forums/attachm...0-setup-sony-mex-bt3900u-metra-aswc-metra.jpg).

 

Yeap, connected the 3.5mm wire from the 70-8114 harness to the Remote In. Did the same thing for Setup 1.

The details of Setup 1 can be seen in my post from yesterday (11:05 AM). The only change is in regards to step f: the black wire of the Metra ASWC is now grounded to the metal cage. The black wire of the radio and Scosche TA02B are still connected to each other but grounded at a different location compared to the black wire of the Metra ASWC.
