Datsun 1200 used dual horns (Japan STD models used a single horn). The horn system uses a three-connector relay, which is bolted to the right-side strut tower just below the ignition coil.
Location
The horn relay is bolted to the right strut tower, under the coil.
The horn(s) are bolted to the radiator Core Support panel.
No. 3: horn relay
Wiring
Horn wiring schematic:
- Fuse 'H' is in the Fuse Box
- + battery voltage is supplied by the horn relay. The horn button switch earths the relay, causing it in turn to supply voltage to the horn. As the horn is a high amperage device, this keeps the power wires out of the steering wheel
- Earth (ground) for the horn is just the fact that it's bolted to the core support panel
- Earth for the horn button goes through the steering wheel hub, which is bolted to the steering gearbox shaft, so it is earthed via the metal of the steering column/gearbox.
Relay Wire Colors
* Green: to horns * Green/white: to 15A fuse in fuse box, Battery side * Black/green: to steering column connector (for horn button) * Case bolts to body (earth/ground)
Early Relay
Stamped on the relay case are:
* H - connector for Horns
* B - connector for Battery (through fuse box)
* S - connector for Switch (in steering wheel)
Late Relay 26321-G1600 7510-
