Time for today's potentially-stupid question. As I keep building my harness, I've got a few spots where I'm tying wires together with window splices, but I'm looking ahead to the intercom wiring and trying to imagine what this will look like.
To be very clear, this isn't a question of what gets connected where, but rather of what those connections will physically look like.
Looking at my schematic, I'm going to have eight ground nodes tied together at the intercom connection: six shields (mic and phones for two seats plus audio/mic to the com radio), plus two sleeve grounds for the headset phone jacks. All those will need to be tied to a ground wire running from a pin on the Dynon intercom to the ground bus on the firewall.
Are people handling this by just doing some sort of inline splices? One big splice attaching eight wires to a window in another wire seems both challenging and ill-advised. Maybe I need to go looking for a different D-sub backshell with grounding screws; the Dynon intercom just came with a basic plastic one.
Photos or descriptions of how everyone handled this would be greatly appreciated.
