    Hello, I have car radios XOMAX XM-2DTSBN6214 and I am looking for a diagram of connecting individual wires in the ISO iso which goes into the radio. I have a cube for this radio but the wires are mixed up because it short circuits me.

    It is worse if someone has shifted the cables in the plug from the radio side ...

    I bought the XOMAX XM-DTSB1010 cube (photo 2) which supposedly fits different models of the XOMAX company. But unfortunately it does short circuit after connecting. Together with a colleague we came to the conclusion that the distribution of cables in the plug that goes into the radio is different. As you can see in the description, everything is correct when it comes to plug A and B, but there is a problem with the radio plug, something is swapped.

    Short circuit? Which fuse is "flying out" for you?
    It remains to examine the connections inside the radio, if you have not already burned something. You can find the mass with an ohmmeter even without opening the radio.
    And from the ISO cube side do you have connections for black to A8, yellow to A4, red to A7?

    At first, the fuse under the dash 20A burned, then I tried again and burned the fuse located in the 15A radio. As for the connection you are writing about (And from the ISO cube side do you have connections for black wire to A8, yellow to A4, red to A7?) that's how I got it. I checked cable by cable when it comes to connecting the cube coming out of the car - iso Xomax cube. From what I looked at German sites radios differ in the arrangement of the individual connectors on the radio. I also found such a cube (the only photo) that fits my radio and after zooming in you can see a different arrangement of wires, but that's all I could find.

    This is probably the end of the fun. This radio did you have new and functional?

    it was new and functional. But I'm not sure if something happened for the radio. As far as I know, I put a fuse in the radio to secure the radio.

    Yes, but not before such combinations!

    I hope nothing serious happened. Until I find the ankle or the right connection. Nothing is known, it may work or maybe not.
    Let this trail go, I bought a radio for a lot of money and through a stupid ankle that was supposed to fit, I'm sitting and I think what's next ......
    Thank you so much for help. ?

    Yeah, especially when you gave + 12V to one of the speaker outputs and where there is + 12V to come, there was a lot ...

    You didn't have this adapter bundle attached? Judging by the operating instructions, it should be included.

    I got the cube, but not the original one, but one that fits the Xomax radio.

    I would advertise with the supplier.

    No way. Radio bought as used.

Topic summary

✨ The discussion revolves around the connection of ISO cables to the XOMAX XM-2DTSBN62 car radio. The user is experiencing short circuits due to mixed-up wires in the ISO connector. Responses indicate that the wiring colors follow standard ISO conventions, but there may be discrepancies in the plug configuration specific to the XOMAX model. The user has encountered issues with blown fuses and is uncertain if the radio has been damaged. Suggestions include checking the internal connections and verifying the wiring against standard diagrams. The user has a non-original adapter that fits the radio but is still facing connection problems.

FAQ

TL;DR: For this XOMAX, the ISO A‑block uses 3 power pins (A8 ground, A4 battery, A7 ACC); “black to A8, yellow to A4, red to A7.” [Elektroda, jdubowski, post #16772595]

Why it matters: Miswired radio-side pins can blow fuses or damage the head unit; this FAQ shows the safe, working pinout and checks for DIY installers.

Quick Facts

How do I wire the ISO power on a XOMAX XM‑2DTSBN62?

Follow the ISO A‑block: A8 ground (black), A4 +12V constant (yellow), A7 +12V ACC/ignition (red). Verify each with a meter before powering. “Black to A8, yellow to A4, red to A7.” [Elektroda, jdubowski, post #16772595]

Why did my 20A and 15A fuses blow after connecting a XOMAX harness?

A miswired loom can short power to the wrong pin, triggering the 20A under‑dash and then the radio’s 15A fuse. Disconnect immediately, confirm A8/A4/A7 with a meter, and inspect the radio loom for swapped positions. [Elektroda, krzys1221, post #16772638]

Are wire colors reliable, or can the radio-side pins be shifted?

Colors often follow ISO, but radio-side pins may be rearranged. If a seller re-pinned the plug, color matching can fail. “It is worse if someone has shifted the cables in the plug from the radio side ...” Always test pins, not colors. [Elektroda, jdubowski, post #16772044]

How do I find ground and power without opening the radio?

Use a multimeter. Find chassis ground first. Confirm A8 is ground, A4 has +12V battery, and A7 has +12V with ignition. “You can find the mass with an ohmmeter even without opening the radio.” [Elektroda, jdubowski, post #16772595]

What is the safest 3-step check before first power-up?

  1. Meter-check A8 ground continuity to chassis.
  2. Verify A4 = +12V battery, A7 = +12V ACC.
  3. Insert correct fuses, then power on. If anything heats, cut power. [Elektroda, jdubowski, post #16772595]

I used the XM‑DTSB1010 “universal” XOMAX loom and got a short. What now?

Stop using that loom. Map each pin against ISO with a meter, then repin or replace the harness. Some “fits many models” looms still short when connected to this radio. [Elektroda, krzys1221, post #16772457]

Could a miswire permanently damage the head unit?

Yes. Feeding +12V into a speaker output or other low-voltage pin can cause internal damage, even if the external fuse blows. “Yeah, especially when you gave +12V to one of the speaker outputs ...” [Elektroda, jdubowski, post #16773273]

My radio had a 15A fuse. Is that the correct value to use after repairs?

Replace like-for-like as labeled on the radio harness or chassis. The case discussed used a 15A radio fuse, which blew during a short. Verify the rating printed on your unit before powering. [Elektroda, krzys1221, post #16772638]

Do XOMAX radios include an adapter bundle from the factory?

They typically ship with an adapter harness per the operating instructions. If yours lacks it, contact the seller or XOMAX support before wiring alternatives. [Elektroda, jdubowski, post #16773273]

I bought the head unit used and got a non-original cube. Any advice?

Do not trust color-to-color with a non-original loom. Meter and repin to ISO A‑block standards, or source the correct bundle. If sold as fitting this model but it doesn’t, raise it with the supplier. [Elektroda, jdubowski, post #16773362]

What does people mean by an ISO “cube” or plug here?

It’s the plastic ISO adapter harness that mates the vehicle wiring to the head unit. In this thread, the OP’s cube had mixed wires, causing shorts. Verify pin positions, not just colors. [Elektroda, krzys1221, post #16771927]

How can I tell if pins are shifted on the radio-side connector?

Visually compare the radio plug to an ISO diagram, then confirm each pin with a meter. If positions differ, depin and move wires to match A8/A4/A7 placement. Colors alone are not sufficient. [Elektroda, jdubowski, post #16772044]

The radio was new and worked before. After a short, is it still worth testing?

Yes, after correcting wiring and replacing fuses, attempt a careful power-up. If no response or distortion occurs, the output stage or protection may be damaged. Proceed only after verifying A‑block pins. [Elektroda, krzys1221, post #16772780]

What is ACC on pin A7?

ACC is the ignition-switched +12V feed that turns the radio on with the key. On this unit, A7 is the ACC input. Confirm with a meter before connection. [Elektroda, jdubowski, post #16772595]

What’s the difference between the car’s under-dash fuse and the radio’s fuse here?

The under-dash 20A protects the vehicle circuit; the 15A on the radio protects the head unit. A hard short can trip both, as reported. Replace fuses only after fixing wiring. [Elektroda, krzys1221, post #16772638]

Should I rely on claims that a loom “fits different XOMAX models”?

Treat such claims cautiously. This case shows a “fits many models” loom still shorted. Always meter-test and verify ISO pin placement before connecting. [Elektroda, krzys1221, post #16772457]
