Is this 1x to 16x riser pictured broken or pictured as designed?

[rhubear]

I bought this riser from Cablesaurus a while ago.  Recently tried using it without any success.

My experience when plugging riser into a 1x slot & connecting molex to it:

cgminer didn't see the gpu.  I have 1 other gpu directly on the MB/pcie16.  cgminer saw the other gpu only.
Win7 device manager saw only an unidentified co-processor which I assume is this gpu.

Picture here shows a loose ribbon wire NOT soldered onto the 16x pcb.   Is this correct, or does it need soldering onto the vacant pin shown on the end of the pcb?

Also, I'm aware of a discussion regarding shorting pin A1 to pin B17 (https://bitcointalk.org/index.php?PHPSESSID=eghhg39gm2e8rp67p52qba3sj7&topic=36061.0).
I'm not clear from the thread whether this shorting is done by default at factory, or whether it needs to be done for SOME motherboards by miners, or whether it needs to be done for ALL motherboards by miners?

Thanks for guidance / clarification!

Sure you need to solder the wire to the pcb. You only have one riser?

you need to solder that wire back on before it will work.

Thought I'd update thread seeing there are at least two replies (tnx to those replying).

After the first reply, I tried soldering the loose wire onto the terminal on the pcb that I thought it belonged. 
Riser didn't work any better.

In the meantime I had emailed Cablesaurus, and they advised that If there was a cable loose, it was probably damaged in transit, and they offered me a replacement product or a refund.  I have accepted their offer of replacement product.

In the meantime, I saw a UK based post from someone doing risers in the UK.  I've ordered a couple of the UK risers.

So if all goes well, at some point I'll have 3 new risers, and can either find a fix for this old one or trash it.  I'm more likely to trash it. 

Thanks for the replies to this thread anyway!
