Not sure if this is the right place for this but, I was inspired by the OP's bench setup so I'm building my own. I'm attempting to build setup for an E60 which doesn't have the JBBR but has a KGM instead. All my components are from a 2010 E60.
However, I'm a bit confused by the wiring diagram in ISTA. Specifically for the KGM, I just want the MINIMUM connections to power on the KGM on so that it can do the translations with the other BUS networks, however there seem to be alot of power feeds to the box which control alot of the down stream features that I don't need on the bench like the door locks, window motors, outside mirrors., etc. These are all pretty thick wires, 2.5 mm, which is like 14 AWG, I don't want to hook up power feeds that I have no need for.
Can someone enlighten me as to what pins are the ones that I need to power JUST to have the KGM module power up and provide the gateway services for PT-CAN, CAN, etc. ?
Based on the supply diagram below, I'm led to believe that Pin 1, on X16759 would be required, but then the pin out table says that pin is "Signal, load cutout"
In the schematic, what do the things about the metric wire gauge size mean (30<18, 30<KGM, 30<10, 30<12, 30<29) I take it that 30 refers to terminal 30, and the 2nd number references the fuse number, but what does 30<KGM mean then? It's a pretty thick wire, so it seems it does have to SUPPLY a decent amount of current, but what does "Signal, load cutout" mean?
For Pin #27 on X16760, it is described as "Wake-up signal, terminal 15". Shall I assume that this means that it is sn INPUT signal when +12V is applied to this that turns this module on? OR is it that this wire is the OUTPUT signal, when the car is at terminal 15?
