Started wiring the Artex345 ELT. The "cup" pin connector are difficult to solder and as Craig M previously said you need about four heat resistant hands and fingers. AEC helped holding the soldering iron which made a huge difference, even with the "helping hands stand". I can not finish the plug as the ground and ELT RX wires are in a loom ( still on test bench ), however I will be able to wire the buzzer to the plug.
