Wiring Diagram
WARNING: Wire colors can vary by year, model and country. Please double-check the wiring in your Datsun 1200 before connecting parts according to this article. You don't want to burn something up! Use a voltmeter or test light to confirm the circuit behavior. There are even one or two mistakes in the factory diagrams.
Overview
Nissan wiring diagrams come in:
- The Factory Service Manual
- The Service Bulletins
- Aftermarket Repair manual, such as Haynes, Gregory's, Chilton and Clymer. Not all include a diagram but older ones did.
Market Differences
Country/Regional Market differences include:
- Hazard (emergency) Flasher system
- JDM: Hazard system with single Flasher
- USA: Hazard system with separate Hazard Flasher and T/S Flasher
- Export non-USA: No Hazard System (OPTION for later Australia utes)
- Headlight switch for Australia has two-position dimmer and positions act differently

1968 x 1280 (2.4 megapixel)
Other RHD
Differences between 1978 Australia and 1978 other RHD
Horn "Low" is optional in Australia * standard for other RHD countries.
Transmission switches * Australia: Spade connectors for Back-up lamp switch * Other RHD has Round multi-connector to: ** Spade connectors for Top Gear switch ** Spade connectors for Back-up lamp switch
Other RHD has: * T/O Cut Solenoid * Vacuum Cut Solenoid * Speedometer has speed switch and attached SW amplifier * Heater is optional * Dimmer dash illumination switch ** Has usual six-connector rectangular connector ** Has additional 1-spade wire for Twist Control ** Two-position: Normal and Dim (not continously variable)
LHD
Left-hand Drive 1978 B120 has these differences from RHD: * Cigarette lighter is not illuminated
Otherwise may be identical as far as colors and wires, but presumably the length of many wires differ.
