Linkhttps://evilution.co.uk/mod/connection-reference-numbers.htm Copy to ClipboardKL is the abbreviation for ‘klemme’ which is the German term for connector / connection. The Klemme KL code tells you how a power or earth wire functions on a diagram.
Used On Smart Wiring Diagrams
KL15 is ignition switched live
KL30 is battery permanent live
KL31 is battery negative, connected all the time

Not Used On Smart Wiring Diagrams
KL50 is ignition position #3 (start)
KLR means ignition switch position #1 (accessory)
Ignition Switch Position
Ign 1 – KLR
Ign 2 – KL15
Ign 3 – KL50
Smart Ignition Switch Positions
Smart only use 3 positions unlike many other cars that use 4.
