B120

Australia

1978 Australia 1200 ute
3 parts each 656 x 1280
Total size 1968 x 1280

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.

B122

Late-model Sunny Truck from October 1989

B210

B210 Early RHD (Australia?):
