Hi following this guide and removed meter/ct/rs 485 connector (16 pins on a kh inverter). Ready to add my two connections from the adapter to pins 3 and 4. Guide says to use red 2 cm connectors left by installer. There aren’t any. Has anyone sourced these say on eBay (link would be great) and how are they fixed to the two wires? Push fit or crimp perhaps. Nearly there once I can get these added.
Many thanks
