Thanks, good info. There was some argument about whether pin 4 or 6 was unused, didn't get confirmed.

Just to note that if you want to use a different supplier for the connectors that doesn't include the terminals (seals not required), here are the needed part numbers:

The 2 and 6 pin connectors need Saab cable terminal P/N 41 15 275. You need 7. These can be substituted by TE Connectivity 2.8x0.8 tab, Junior Power Timer, Std, 0.5-1.0 mm² wire,
valid P/Ns are: x-962841-x (strip) or x-963745-x (loose piece).
Alternative P/Ns are x-964294-x (strip) or x-964293-x (loose piece).
The x's in the P/Ns above are for material/finish variants, and are not critical. Choose at least tin plated if possible, or pre-tinned.

The 12 pin connector needs Saab cable terminal 91 20 957 (NLS-USE 12789796). You need 8.
These can be substituted by TE Connectivity JPT receptacle, Std, 0.5-1.0 mm² wire,
valid P/Ns are: x-927775-x (strip) or x-927783-x (loose piece).
Alternative P/Ns are x-964284-x (strip) or x-964283-x (loose piece).

You also need a ring terminal for the ground wire. Saab P/N 78 29 617 or equivalent, to suit M6 stud.

Wire should be at least 0.5 mm² in area, except power wire (pin 6 on CD changer) should be at least 0.75 mm².
Make sure to use twisted wire for the CAN bus cable, or twist it before cutting to length/assembly. The left and right channel pairs are balanced and should also be twisted, preferably with different numbers of turns per unit length.

Also, there is some flexibility on connector P/Ns as well; should be able to use 2-962344-1 as well, for example. Finally, if you're never going to hook up a real CD changer and want to save the 12-pin connectors (827230-1 and 827229-1), you can just solder your made up harness direct to the BlueSaab - bearing in mind it'll be harder to remove later. Or just use another generic pair of 8-way connectors at the BlueSaab end.

Edit: added mention of twisted audio pairs and emphasised P/Ns.
