Horn (Circuit F-3)
Z-78wiring diagramTwo horn-control branches: with air bag system (via diagnostic module Section S pin 85, S-06 horn switch, S-07 passenger-side air bag module) vs without air bag system (via E1-01 combination/horn switch). < >...K8 DOHC; E1-01 < > variant is with cruise control. Ground wire colors at the bottom rail were not legibly printed (marked ??).
