Airport wireless card AR5BXB112 Cables and card connections broken

I have opened my iMAC and unfortunately I accidentally broke the connectors of the cables to the airport wireless card. I also broke one of the connectors on the card itself. I have bought a replacement card but I haven't managed to get replacement cables. Does anyone know where I can find some. Also, how do I replace them?

Thanks Dan for responding. So the three black cables there. I have just put the card to show the connections there. I hope this is clear, if not I can post more pictures

So I can manage to narrow down the issue for all the helpful comments here (thank you). I think the cable to CH1 doesn’t have the crimped connector that is then connected to card. The picture below is with the old damaged card and I have a new card with all its connectors. My problem is how do I fix that black cable.

Answer this question I have this problem too

Is this a good question?

Are you asking about the antenna cables? Can you post a picture so we can see things.

I’m not sure if that’s the correct name for the three black cables in the comment and picture

Looks like one of the connectors has came off. Pads look ok so easy solder job if you still have the part. From the pic the cables look ok

@strongbow - Don’t be to quick here, the coax connector is like your TV coax cable. These are crimped on connectors as you have a middle wire the an insulator (dielectric) then a covering shield.

@danj The connector that has came away from the board not the cable. Even I’m not stupid enough to try soldering these cables. Obviously misunderstood what I meant by ‘connector’. The small metal piece. Usually when it comes off the board is still stuck inside the cable end connector. Same as mobile phones use for signal etc.

Yes these three wires are the antenna coax lines. Two are for WiFI the third is the Bluetooth.

Can you post a nice tight and in focused picture of the damaged cable and the connector if it’s loose. So we can see if it’s salvageable. Otherwise you have a bit of work to replace the cable. Tracing the line back to the antenna unit so we can ID which is needed as the length of the cables are different.

I managed to isolate the cable that has the broken connection. It is the connection to CH1 on the airport card goes into the aluminium plate. This plate is the one on the opposite side of the apple logo on the outside of the computer. I assume that the logo is the Bluetooth receiver. I think I’ll need to replace this cable so any help with the instructions and also where I can get the cable from.
