spent all day, apparently not achieving much! Decided to tackle the bit Ive been putting off... trying to unscramble and make sense of the wiring loom for the GTN750 Flightstream, TRX1500, DME and Transponder. The DME and Tpx are in the back, so I need to make new looms. Unfortunately I need different wire and connectors after getting things sorted in my head, I couldnt do the work! Wired the loom from the Transponder to the GSU25 and GTN750, running it up the SB lower conduit (2) to the panel.
