Aerpro Harnesses - Steering Wheel Controls 101 

Hi Adam, Pioneer stereos require the handbrake wire to be connected and the handbrake engaged before certain settings like the steering wheel control setting can be accessed.

@@aerpro hello, thanks for the reply works fine now 👍

And only connect the 3.5mm to the jack right? I don’t also need to use the key 1, key 2 and ground wires? Because I tried that too

Hi, you are correct, it is only the 3.5mm jack which needs to be connected to the Clarion FX450. The key 1, key 2, and ground can be insulated and left unused. There will be 3x looped wires on the patch lead (orange, green, and purple) and of those, the purple loop will need to be cut. Once cut the module will need to be reset by unplugging it from power for 1 minute and then reconnecting. Once this has been done, check to see if your steering controls are working.

@@aerpro thanks team, that got it. Much appreciated

Hi, if you have purchased a APKWPL patch lead, the single wire from that will connect to the blue wire with the yellow trace from the Kenwood stereo. Be sure to disconnect the module from power for one minute to allow it to reset once this connection is made.

What harness did you have cause mine just doesn’t work at all

What about the pink wire and the other loose ones? I’ve lost my cruise control using this

Hi Kurt, there may be other reasons that the unit is not powering up correctly. It would be best to get in touch with your local car audio specialist for assistance. You can also contact our customer service team on 03 8587 8888 who can run through some fault finding techniques if you like.

Hi, have you been incontact with Automotive Superstore as yet for tech support? Their team will be happy to assist with fault finiding or installation if needed.

Hi Enrico, There is a loose blue wire with a bullet connector on the end which is part of the CHMZ7C harness. This blue wire needs to be connected to the blue wire of the stereo harness which will trigger the factory amplifier to switch on.

Hi, the Narva 56048BL would be the most suitable. www.narva.com.au/products/56048bl/5-0mm-male-bullet-terminal-blue--14-pack-

Hi, is it a factory fitted Toyota reverse camera you are looking to connect to the Sony or is it an aftermarket reverse camera?

Hi Bruce, it is best to contact your place of purchase for a replacement if your module is faulty. They should also be able to assist with fault finding prior to organising the replacement if needed.

Hi, Yes, the purple wires will need to be connected to have your aftermarket stereo switch over and display the factory reverse camera.

@@aerpro Hi, I tried to connect all the patch leads and they all fit but the head unit could not have the factory reverse camera signal. Any reason for it? The head unit can detect the reverse gear signal tho. The head unit is Sony XAV-AX5500. Thanks.

@@aerpro I also placed the green (park brake) wire to a metel bolt in order to ground it while I was trying the reverse camera but the camera still did not either. I understand Camry factory camera uses 6V and the 6V output chip (L7806CV) of the CHTO15C got very very hot immediately after I turned the power on, could this be the cause ?

@@austinliuyilun it will be best to contact our technical team at tech@tdj.com.au in regards to this as they will be able to assist further.

Hi Peter, unfortunately we do not currently have any interfaces to suit your BMW motorcycle. For assistance in custom wiring a solution it would be best to speak with your local car audio specialist for advice as they will be able to test and assess the existing wiring.

Hi, the handbrake wire from the CHMZ12C harness and the main harness of your stereo will need to be connected together to function correctly.

Hi Timothy, no the APP030 primary harness will not be needed as the CHGM7C steering wheel control harness will act as the primary harness in your case.

Front speakers work, steering controls work, Reverse camera works, The light green park break wire should that be earthed ? Would the issue have sonething to do with the blue wire ?

Hi Sam, the only reason you may lose audio in you rear speakers is because you may have missed one of the connectors which connects to the vehicle harness. Also be sure your Hilux has rear speakers fitted as not all models came with speakers fitted in the rear doors.

Cheers for that. Took the door cards off no rear speakers. How random

any luck mate ?

You could have to go into settings and manually enter the controls

Same here, they said it would be easy lol. Way over my pay grade

I’m having the same problem

Turn source off in settings and try again

Hi Phil, you will also require a patch lead (APUNIPL2) to connect the steering wheel control module to the steering wheel control input on the rear of the JVC stereo.

@@aerpro that patch lead came with an FP9227K unit install kit, my son hardwired the wired to the key 1 & key 2 wiresbut it didn't activate the steering wheel control, we watched the videos of hardwiring doesn't work.

I actually need a video showing how to connect the JVC KW-M150BT to the FP9227K SWC interface for the Hyundai Santa Fe 2010, all but this car installation with both items I have mentioned.

@@aerpro it says I will need the LD-SWC-F3.5 but it still doesn't show me how to hardwire after connecting the patch lead plug into the LD-SWC-F3.5 then which wires does it go to.

@@thekoolestkat1 it will probably be easiest to call our customer support line when you have the vehicle available to work on and our team can walk you through the details step by step. Our number is 03 8587 8888

Hi Edde, you can still go back and follow this procedure. You will simply just need to disconnect all harnesses from the vehicle for at least 1 minute prior to following this procedure to allow it all to reset.

@@aerpro thank you I did this and also mapped the buttons on my unit and it worked. Very happy with the result.

Hi Tara, to access the steering control menus on most headunits, the handbrake wire needs to be connected during installation and the stereo needs to be in standby for the function to be accessible in the menu.

@@aerpro we connected the handbrake wire, how do we put it in standby mode?

@@taralawton1353 it will depend on which stereo you have installed. It would be best to consult the user / installation manual of the stereo.

Connect that park wire to a -12v ground and it won't be a problem

Hi Nicholas, for further technical assistance you can contact our customer service team on 03 8587 8888 if you like.

Hi Alex Trey, In the particular harness pictured in the video (CHIZ2C) there is no reverse trigger available behind the factory stereo. As such, the reverse wire (purple/white) from the aftermarket head unit will need to be manually connected to a reverse trigger wire.

Hello Juan, Unfortunately we do not currently offer a Bose compatible complete kit for the Mazda 3 BL 2012 however if we buy the parts individually we can substitute in a BOSE compatible Steering Wheel Control Interface. So for a Mazda 3 BL 2012 Bose system with a Kenwood DMX9720 XDS you will need: FP8072 (Fascia) CHMZ8C (BOSE Amplified) (Steering Wheel Control Interface) APA55 (Headunit Antenna Adapter ) APP8KE7 (Headunit ISO harness) APUNIPL2 (Patch Lead) These items will make up what you needed from the complete kit but now compatible with your BOSE system. Please let us know if you have any questions

@@aerpro I’ve ordered last week the parts below… FP8072 (fascia) CHMZ8C (Bose amplified, sw control interface) APPK9KE7 (ISO harness and includes the correct patch as stated in your website). Do I need still the APA55 (headunit antenna adapter)..?? Regards…

Hey @@juanpalomino7043 Yes you will still need the APA55 Headunit antenna adapter

@@aerpro Thanks..!!

@@aerpro All parts have arrived and I did proceed with connection as shown in these video starting from the headunit and working back to the vehicle. I ended up with only two harness from the headunit (main harness and antenna). My vehicle has 3 harness which are. Main harness, antenna harness and AUX in harness. Should I leave the AUX in harness unplugged ?? Or I missed the Aerpro APMZAUX harness. Or my HU does not need these harness. KENWOOD DMX9720 XDS Thanks in advance

Hi Fili, is your Honda Stepwagon an Australian delivered vehicle? I don't believe we have a listing for it, but if you could provide us with an image of the factory stereo connector we may be able to match something up for you.

@@aerpro Can you contact me on a different plaform

@@fililemoa9079 you can contact our technical sales team at tech@tdj.com.au for further support.

Hi Benjamin, if the tech team was unable to assist over the phone it may be something else to do with either the headunit or the wiring / connections. Best advice would be to visit your local car audio specialist who will be able to diagnose it further for you in person.

@@aerpro Thanks for your easy and poor answer. I exactly followed the manual instruction and also the video methods... On my side, I suspect a defect an Aerpro equipment so I will not recommend Aepro equipment to anyone. Due to your lack of support, can I send the bill of the car audio specialist to aerpro?

Could you please confirm me at least the setting configuration which have to use for my Nissan Xtrail 2012 (T31 model)? The model of my previous autoradio is PP-3091T and serial number 0033382

@@benjaminmelin9441 You are correct to remove all plugs and modules in between dipswitch changes, 30 seconds wait time is ample. It is important not to have the parts plugged in as the internal chip will not recognise the changes if it's plugged in. Also, stick to the dipswitch settings in the manual only. aerpro.com/sites/default/files/manuals/chniuni_instructions_1.pdf If you are getting results from the buttons, but they incorrect, you can try swapping the blue and green bullet terminals on the main harness. This swaps the two Key wires for the controls, Nissan did alternate these wires depending on the system. If you are not receiving any results at all from the button presses, this could also indicate the presence of an auxiliary bluetooth module. In these models, they are commonly located in the rear quarter behind the plastic trim. You will be able to access this from the rear of the vehicle. In the packet for the CHNIUNI you should have the bluetooth bypass plug. Not using this will inhibit the steering wheel controls, as when the factory radio is removed, the bluetooth module will de-power and not allow the control wires to flow back to the radio, this bypass plug allows this connection to remain complete. During all this, as all aftermarket radios can differ, ensure you are utilising the radios internal options for enabling steering wheel controls. You may find yourself in a situation where the harness is setup correctly, but the radio is not listening to them.

@@aerpro Hi, so I installed the bluetooth by pass (I wanted to do it when the steering wheel was working but ok , I did it now)... I tried again the 4 setting of the manual (I did it twice and unplugged every time all the wires and wait 2mn before a new setting), but it is still not working again and I lost 2h again! I checked also the setting of my Sony autoradio and the steering wheel is "on" or available... I connect also my old nissan autoradio, for checking the steering wheel, and it is still working... so do you have other option or tips to propose? except asking to Supercheap Auto a new Aerpro Steering wheel control harness... I suppose something is wrong with the one I got... looking forward to hear from you, thks

Hi Trevor, One end of the patch lead will connect to the steering wheel control module while the other end will depend on the make and model of the stereo you are installing.

Hi, For tech support on our products please send an email to tech@tdj.com.au and we will be able to assist further.

@@aerpro yeah I have three times now with no reply thats why I asked here

@@kanes69er please send me an email directly to marketing@tdj.com.au and I will follow it up with the sales team.

@@aerpro i did before I even shaw this video and contacted threw your web page to all with not one reply but I'll try again maybe fourth times a charm

I have tried all of the above steps and still can’t get the steering wheel control to be selected. It stays gray.

Hi Ian, what make and model of stereo are you installing? Some stereos require the steering control function to be switched on in the settings of the unit.

@@aerpro it’s a pioneer DMH-Z5350BT

@@toofa68 that model of Pioneer will require the steering wheel control function to be switched on in the settings menu of the stereo. The following video may help you with the process. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-M8rOpgse8vI.html

@@aerpro thanks guys. I will try this tonight

@@aerpro still not working the steering wheel control is blank/I highlighted. Followed both videos to the letter.
