I guess it's possible that the difference in those cables is the ibus lines being switched; everything else *should* be the same...(although you would think *everything* would be the same, so who knows) but if the ibus isn't connected properly then yeah, things won't work right. It could be that reversing these wires is causing enough of a bus problem that the car can't talk at all. OR if one of those lines is being grounded or pulled to 12v, that would disturb the bus also. 

Thanks for providing that info on the harnesses!

Hi there,
A fellow saabist hooked a v3.3 BlueSAAB in his 2003 9-5 using the harness 400129243 and he reported it working absolutely flawlessly . Many thanks to him for the feedback !

When I google the two parts with their reference number, I find that 400129243 is dedicated to 9-5s where 400111738 goes to 9-3s. I suppose there are slight differences in the wiring setup that may cause Herbert's issue with the 400111738 harness in his 9-5.

The best way to solve that would be either to order the correct 9-5 harness : https://www.esaabparts.com/saab/parts/400129243 or to identify every incoming cable from car's harness (12V, GND, CAN H, CAN L, R+, R-, L+, L-) and connect it to the correct cable going to BlueSAAB... maybe a bit painful but worth the try.
I suggest Herbert to start with this before going into BlueSAAB's hardware or even software. Hope this would help.
