Best answers

How should I connect the Opel/Corsa D ISO power adapter wires: which one is permanent battery +12 V, which one is ignition-switched, and where should the blue antenna power lead go?

Connect the Opel cube/ISO adapter according to the diagram: the yellow wire is the permanent +12 V battery feed, the black wire is ground, and the adapter is wired correctly that way [#17007296][#17007675] If you need to power the antenna amplifier, connect the blue antenna wire to the red ignition-switched + lead so it gets power only when the radio turns on [#17007521] The blue wire is only needed for an antenna with an amplifier or an electric mast; if the antenna is passive, nothing needs to be connected there [#17007770][#17008097]

    Good morning, I have 3 questions to join experts. It's about dispelling doubts :) because, unfortunately, I found in the network 2 different descriptions of the power cube iso ...
    1) The request to look at the photo on the black-mass is ok, but as for the yellow one I do not know if it is "under the ignition" or "under the 12V battery," someone will help?
    2) Possibly if this loose red is for 12V akum. this is where to attach it to the Opel cube (2foto)
    3) Antenna - constant power (because it's probably not the same as ejecting), the blue cable goes out, I plug in where, or maybe the link with which?

    Thank you very much.

    Thanks, so it comes out that the yellow radio cable is a combination (as I wanted) with a plus from the battery, and not just from the ignition.
    There is the issue of the blue cable from the antenna power supply, no problem I will bump into the free "pin" of the cube, but should I understand that the radio will supply the power needed to amplify the antenna signal; / because I thought I had to pick up, for example, plus power? (this photo is an adapter from "opel" to 2iso, and soon I am going to the store for a radio and with it will be an adapter from 2 iso to 1iso

    PS. In the large "Oplow" cube from the picture above, these 2 power pins are in the right place, because I also found such a pattern in the net (it is also in Opel's cd30) and is "something else ... because GND (mass) is from the side and not over a plus - if I take it right from the picture.

    You can take the blue wire to the red one after the ignition and then the amplifier will work. This plugin with this scheme is not sometimes the radio of a different model than yours.

    Are there any colors from this cube sticking out of this peg, what did you mark? The diagram is from the Opel-cd30-mp3 cube, that is under the Blaupunkt radio and that's why you do not like to leave.

    So two cables from the power cube, ie yellow and black, enter a large Opel cube - mark the attached picture.
    I do not want to suggest, but should not the yellow be in the black spot (plus from the battery), and black on the left here where GND, or somewhere above where is the CE-?

    I will go down to the car, take out the radio and see what cable colors are hidden in the installation cube in this particular pin location, like yellow / red and black as probably GND will probably be okay?
    Radio, the installation is original Corsa D, and I bought this adapter with a frame to install a better 1DIN radio, for example Sony, JVC, because I have to go from a strange opel cube to 2 iso, then to 1iso eg Sony.

    Well, would it be nice to recommend because different radios have different outputs?

    I removed the radio and took a picture of the installation coming out of the car to the radio and in my opinion it is as I thought. I attach a photo like on the buying block should (probably) be pinned.
    I'm well-suited?

    Thank you so much.
    When the player comes, I will sleep it for a short time, without a solid pocket fastening and see if it plays ... I will also put on this antenna cable as you said blue with blue, see if there is a better signal than without connecting them, because maybe the blue plus would have to be given I will see, because you can see the spartolili cube-adapter and was supposed to be for this model ... For now, thanks!

    Blue cable gives power to the antenna after switching on the radio if you have an antenna with an amplifier or an electric retractable antenna?

    This is a standard antenna on the roof (nothing sliding with the motor, etc.), i.e. how I turn on the tuner, the equipment say, for example. The Sony player sends the voltage on the blue cable to this antenna amplifier, because that's how I understand it.

    Yes, if this antenna has an amplifier. Because if there is no such a cable, this antenna has no need to hook anything.

    Everything is already mounted, it is a pity that such a frost. I corrected the cube connecting with the Oplowska installation in the matter of pins (post 11), as it should be (from the beginning in the shop ;) ). The player mounted, plays nicely, connecting to the radio. Greetings.

FAQ

TL;DR: For Opel Corsa D/Quadlock-to-ISO installs, 1 blue antenna-control wire powers only when the radio is on — “Blue cable gives power to the antenna after switching on the radio.” Map yellow=BAT+, red=ACC, and correct any mispinned adapters. [Elektroda, Pedros050, post #17007770]

Why it matters: This avoids no-sound, memory-loss, or antenna issues when fitting aftermarket 1DIN radios in Opel vehicles.

Quick Facts

Which wire on the ISO harness is constant 12 V in an Opel Corsa D?

Use the yellow lead for constant battery power. It maintains presets and clock memory. This thread confirms yellow goes to the battery feed in the Opel-to-ISO setup. Ensure the adapter’s yellow is on the Quadlock’s permanent +12 V pin before final assembly. [Elektroda, k52, post #17007452]

Which wire is the ignition-switched (ACC) feed?

The red lead is the ACC feed. It powers the radio only when the key is on. You can also piggyback the antenna/amp remote (blue) to the red ACC if your antenna amplifier expects switched power from the ignition. “Then the amplifier will work.” [Elektroda, Pedros050, post #17007521]

What does the blue wire do on Opel/ISO radio looms?

Blue is the antenna/remote amplifier control. The head unit outputs +12 V on this wire only when the radio is turned on. This triggers an amplified roof antenna or a powered mast. Quote: “Blue cable gives power to the antenna after switching on the radio.” [Elektroda, Pedros050, post #17007770]

Do I need the blue wire if my roof antenna isn’t amplified?

No. If your antenna has no built‑in amplifier or electric mast, you don’t need to connect the blue lead. The radio will still receive through a passive antenna path. If reception is weak, verify whether your model actually includes an amplifier before adding the blue feed. [Elektroda, Pedros050, post #17008097]

Where should the loose red wire from my ISO harness connect on the Opel Quadlock?

Connect the red ISO wire to the Quadlock’s ignition-switched +12 V position. This ensures the radio turns off with the key and prevents battery drain. If your antenna amp needs switched power, you may tie the blue remote to this red ACC feed. [Elektroda, Pedros050, post #17007521]

How many power-related pins should I expect on the Opel Quadlock?

Expect two power pins: one permanent +12 V and one ignition-switched +12 V. This matches the discussion where the layout shows two distinct power positions in the Opel cube before repinning the adapter. Verify these before powering your new head unit. [Elektroda, k52, post #17007452]

How do I adapt an Opel Quadlock to an aftermarket ISO radio?

Use a Quadlock-to-ISO adapter harness and follow the provided pin diagram. Plug Quadlock into the car, ISO ends into the new radio harness, then secure the cage and trim. This is the recommended path for Sony/JVC 1DIN units. [Elektroda, Pedros050, post #17007296]

Quick 3-step: How to wire an aftermarket radio in a Corsa D?

  1. Fit a Quadlock→ISO adapter and confirm pin mapping against the diagram.
  2. Connect yellow=BATT+, red=ACC, blue=ANT/REMOTE, black=GND on the ISO side.
  3. Test power and FM reception before final mounting. [Elektroda, Pedros050, post #17007296]

My adapter seems mispinned. What’s the fix?

Repin the adapter so yellow goes to permanent +12 V and red to ACC in the Opel Quadlock. After correcting the pins, the poster reported a clean install and proper operation. Symptom resolution included stable power and good audio. [Elektroda, k52, post #17017153]

Will a 1DIN Sony or JVC fit and work with this approach?

Yes. The thread’s Corsa D used a fascia kit plus Quadlock→ISO, then an ISO→radio lead to a 1DIN Sony/JVC. After mapping the power and remote leads correctly, the setup worked as expected. Ensure the frame and pocket are secured before driving. [Elektroda, k52, post #17007588]

Does the radio supply power for the roof antenna amplifier?

Yes. When you select the tuner, the head unit’s blue wire outputs +12 V for an amplified roof antenna. This is how many aftermarket units control antenna amplifiers and powered masts. “The player sends the voltage on the blue cable to this antenna amplifier.” [Elektroda, k52, post #17008087]

I see different Opel pinouts online—could my diagram be for another radio?

Yes. Some diagrams reference the Opel CD30/MP3 (Blaupunkt) pinout, which may differ from your unit or adapter. Always match your vehicle’s harness to the adapter scheme before powering up. Misalignment here is a common cause of no‑power issues. [Elektroda, Pedros050, post #17007554]

Can I link the blue remote to red ACC to wake an antenna amplifier?

Yes. If your antenna amp needs switched power with ignition, connect blue to red ACC. This gives the amplifier power when the key is on and the radio requests it. It’s a practical workaround when the car loom doesn’t feed the amp separately. [Elektroda, Pedros050, post #17007521]

How do I know the final wiring works before full install?

Bench‑test in the dash opening: power on, verify presets save (yellow), confirm key‑off behavior (red), and check FM strength with blue connected. The poster did a short test fit first, then finalized the mount after confirming success. [Elektroda, k52, post #17007705]
