No. No grease on it. Probably just light reflection.Is that dielectric grease on the connector face ???
Saab doesn't use splice packs like GM? You would figure with all the GM influence they would. On all my cars, the parallel-wired low speed bus comes together at an accessible, removeable header plug. If you're trying to diag a bus problem, you can remove the plug and jumper each individual (or more if you make a custom jumper) module to the DLC line....then test. Easy way to rule out bad modules without disconnecting each one. High speed devices are still daisy-chained however.It seems rather excessively ridiculous to have all of these computer modules in this car, tucked behind a dozen different panels, screws, locks, and other items, and the engineers never thought to design the system so that it could show you what is working and not working unless you unplug each one individually. That is messed up.
