DIY - Installing Dasaita MAX6 unit on '17 BRZ w/Backup camera, Aux In, and USB
This guide is for the DASAITA unit, which I can confirm has a different black power connector pin-out than the Joying Akuma installed in his car.
The Basics Out of the box, almost everything works with this this Dasaita stereo. The Steering Wheel Controls (SWC), GPS, Bluetooth, WiFi, and radio all work flawlessly. However, a few things do not: the front door speakers+factory AMP, the backup camera, the front USB and the auxiliary input all do not work out of the box. However, they are pretty simple to fix once you learn how to do it. When ordering your unit, ask for the Toyota Dasaita harness. It should come with both a 24 and 28-pin connector in the harness, but specify which connector you want just in case. To start, you will need a few tools and supplies. Get them before you start with the project:
Additionally, you will need:
The main harness has the 10+6 pin connectors, a 24 and a 28-pin connector, a radio antenna connector (identical to metra 40-LX11), a reverse orange cable, and a brown parking brake cable. We will use all of these except the 24-pin and the brake cables. The 24 and 28-pin cables are only wired for SWC out of the box, so we have to add a few cables to the 28-pin connector and this will be half of the job, the rest will be soldering these to the main harness. Part A - Repinning Grab the AX-SUB28SWC and a tiny flat-head precision screwdriver, like the ones for fixing glasses. I used a 1.4mm, but it barely fits in the hole and a smaller one should work better. Insert the flat head in the dash (-) shaped hole, and press with all your might. You might need some kitchen paper tissues to hold the connector in one hand and the tiny screwdriver on your other hand without bruising your skin. Remove the following pins:
Part B - Cutting and Soldering We are almost done. We need to solder our cables together and you will have a custom-made plug-and-play harness for your shiny new Dasaita unit. We will solder about 5 solder joints as follows:
The Finished Product Important: for all of these, remember to put a shrink tube as far away from the solder joint as possible. After soldering, slide the tube on top of the joint and use the heat gun to shrink wrap it. Please be very careful when soldering as you can shrink the tube prematurely with the heat of the iron and the result is a PITA to fix. Before cutting them, join all the relevant wires together and tape them if you want an idea of where everything will go. Measure twice, mark with a sharpie, and cut once. Finally, I strongly suggest practicing a few solder joints with the excess cables you get or cut. This made a huge difference for me. That is all, you should have a fully functional plug-and-play dasaita harness. The last thing is to plug in the adapter (D) into the headunit to get aux In and backup camera Input, the (B) and (F) cables for two additional USB ports, the AX-SUBUSB2 to get front USB, and the GPS and WIFI antennas for their respective uses. Also included is a USB SD card+adapter with GPS data for the native GPS app, so plug that in if you want, and an external mic which I'm too busy and too lazy to route at the moment. When removing or connecting the stereo, remove the black terminal of the battery to be safe. edit: Please connect and route the external mic to the front of the speedometer/back of the steering wheel, it makes a huge difference as the internal HU mic is garbage. The external mic works wonderfully. Last edited by Plumbus; 10-23-2020 at 01:23 AM. |

METRA 10 AND 6 PIN RADIO WIRING HARNESSES - mostly useless. Buy joying harness, or use the one that comes with your stereo. http://www.ft86speedfactory.com/metr...-forester.html Notes 1. Apparently, headunits with integrated amps/DSPs do not work with the twins. The twins have an external amp on the trunk on the driver's side. Factory amp needs an analogue signal while amped headunit outputs digital. Do not get a digitally amplified unit!! Confirmed by JstnBrdy Turns out this is BS. "Integrated" DSP is software only. The hardware part is the SPDIF connection for digital output, but the DSP part can be enabled or disabled so you can output analog signal for factory AMP using the regular harness cables. Buy DSP unit without worries.2. FRS and 86 cars use a separate 24-pin harness/connector for the backup camera, 2017+ BRZs use the 28-pin connector for the same thing. Steering wheel controls are also on these harnesses. Confirmed by itsAlex 3. 2016+ BRZ moved the AMP cable from 10+6 pin cables to the 28-pin connector, pin #9. Sigh. Lots of people running around without front door speakers working. 4. You can alternatively use a wiring interface to get SWC. Expensive, complicated, and a waste of money, but it works. Much better to use 28- or 24-pin adapter directly. 5. If you have speaker hum/hissing/high pitch noise, see Pumpkibbles' post. https://www.ft86club.com/forums/show...17&postcount=4 Thanks to: Akuma147, nothing in this guide would be possible without his pioneering efforts.

I need more information. Did you solder the harness yourself, or you just took the harness out of the box and plugged it? Did you use this guide or one specific for FRS?
Finally, is the "OEM audio plus system" the infamous JDL audio system? |

I just plugged in the harness as it came.
Here is the site for the system https://oemaudioplus.com/scion/frs/

Here are three things to think about: the Dasaita headunit has a built-in DSP, but it requires you to use the RCA inputs, so that rules that out. For our cars the headunit must use the amp located in the trunk. The factory amp is connected to the headunit through the factory harness, but you must modify the DASAITA harness to power the factory AMP in the car. In the FRS, the factory amp turn-on is on the 10-pin plug, pin 9. You need to wire the cable on pin 13 of the black dasaita connector to the previously mentioned wire on 10-pin plug. For the BRZ, you must solder the pin 9 cable from 28-pin connector to pin 13 cable from black connector because amp pin is located differently. This is detailed in my guide, and was required so the big door speakers could work. The biggest problem is you have no sound, which did not happen to me because only the door woofers are powered using the trunk AMP. The oem audio plus for FRS advertises plug and play harness with factory headunit, so it should theoretically work just fine with aftermarket unit, except for the modifications to DASAITA harness. A local stereo expert should be able to help you I'm sure. Let me know if you ever fixed this problem! edit: a few references http://www.ft86club.com/forums/attac...4&d=1340370296 https://oemaudioplus.com/wp-content/...Q_Version2.pdf Last edited by Plumbus; 03-10-2020 at 04:49 PM. |

I found out what it was! The internal dsp was messing with the OEM audio plus system.
Now it works great !!

I'm not entirely sure how an aftermarket amp is wired. Does it power the door speakers? Then it would replace the factory one and be wired directly to the car wiring, plus powering the subwoofer and you would need to wire the subwoofer signal to the center console wire loom. Or possibly you would need to wire the aftermarket amp directly to the center console with RCA plugs at the end to connect to the headunit. In my case I only had to power the factory amp using the headunit 12v, and only had to modify the Dasaita harness for this. You are going to have open a new thread and hope a car stereo expert to chime in or go to a car stereo board or simply go to a car stereo shop, the experts would know how to best approach it. Sorry I can't help more. |

This is a great thread - I keep referencing it.
(n00b?) question: I purchased the Joying Hilux harness, and it only has a few pins on the 28-pin harness (for steering wheel controls and aux, I believe). The wire to turn on the factory amp is a bare wire - it doesn't have the pin on the end of it, like the ones that are already inserted into the harness do. Is that something I can buy somewhere? (I'll also need some pins to wire in my factory reverse camera.) |
