The Leyland Parts Catalogue (and Moss) show both a 'battery cut-off' relay for '76 on', and an 'ignition switch' relay from '77 on'. The former is for North America only. Were both of these relays fitted from 77 on, plus the starter relay making three? Or did the 'ignition switch' relay replace the 'battery cut-off' relay in 77? Thanks, PaulH.
