The two fiber optic cables get released from the main connector body as in step 2 of the instructions. After that they can be separated from each other so they can be put into the loopback connector.

Step 2 says to "Detach the fiber-optic connector housing from the main connector." As I meant to explain, my problem is that there is no fiber-optic connector housing detachable from the main connector. It's all one integrated piece of plastic.

 

It may appear to be one piece but it actually is not. I have taken these apart before. I assume that this is the connector that was plugged into AMP1.

This document may be of some additional assistance:

BTW saabdocs.com is a great repository of instructions for Saab accessories.

 

Post #83 shows pics of me taking apart the connector on the CD player end, I'd imagine its the same at the amp end?

Actually the set up is different for amp1, but thanks for the detailed pictures, which may be useful in any case.

 

I guess I'll take out the front seat so I can have a closer look. Thanks.

 

You should not have to take out the seat. Just put it as far forward as it will go and raise it as much as possible. That should give you just enough clearance to do what you need to do.

 

I've done that but so far haven't been able to see what I'm looking for. Will give it another shot.

 

So if my amp1 stopped working as well, replacing this could possibly make it work again?

 

It will by-pass your amp not make it work again. You will regain functionality of your radio and blinker sounds but will lose some of your speakers.

Also, notwithstanding the helpful feedback I received on the forum, I was in fact unable to disengage the fibre optic connector housing from the main housing. It may be that there are different housings where everything is an integrated unit, or it may be that I was unable to gain the access I would need to perform the disengagement. Everything is very tight in there under the driver's seat, particularly if the exposed cable run is very short, as I found to be the case.
I ended up buying a used amp1 in good condition on ebay for $250 - a comparatively good price - and simply replaced the amp. Everything is working now as it should.

 

In regards to the loopback, is the Optical Cable Connector (Onstar Delete) the same thing as the Etadyne loopback? I'm hesitant to buy from Etadyne because I've heard they're out of business now, and the GenuineSaab part seems to be cheaper. Thank you!

 

Yes. It's the same part. PM me your address and I'll mail my etadyne part to you gratis as I no longer have a use for it.
Etadyne is still in business.
