Mid-model utes and later Sunny Truck came with intermittent wipers. Intermittent wipers were an option for the 1200 starting in 1978 April. Then became standard fitment starting October 1981. They are just like the regular switch with two positions Slow and High, but with another position which is intermittent every six seconds. So instead of OFF plus two stops, it has OFF plus three stops. It uses the same wiper motor as all 1200s, so the wiring harness does not need to be modified. The only downside is they are not variable intermittent.

1978-up B120

This is a direct bolt-in for earlier 1200s, except for needing to wire up one connector. You would need the amplifier and wiper switch, and sub harness.

  3. Fit new switch to the dashboard
  4. Connect one end of SUB HARNESS to the dash wiring
  5. Connect last end SUB HARNESS harness to AMP
  6. Screw the AMP to the steering post
  7. Connect BAT wire to fuse box 'W' terminal
  8. Connect EARTH wire to an available Earth point

Switch Identification

  • 1970-1978 wiper switch: square 6-connector with blue wires
  • 1979-up Wiper Switch: rectangular 6-connector

The newer Wiper Switch looks much like a headlight switch, but has one blue wire

Wiring A

Where the SUB HARNESS cannot be obtained from a donor 1200, you can make one like this.

22440.jpg
Use connectors from an old Datsun wiring harness (non-1200 donor) -- so that in your 1200, there is no cutting of the harness at all to fit the intermittent switch and AMP.

Then modify it as follows:

  1. the Park wire is cut and both ends sent down to (to the AMP)
  2. the new Intermittent wire (the sixth wire) is added. It goes down to the AMP too

Mount the AMP (black box) somewhere appropriate. I fitted it to the pedal box, with the same screw that fastens the Flasher. I chose to earth it right there (black wire).

Wiring B

Diagram from 1978 Australia B120 Factory Service Manual. However this is for a two-connector switch. The diagram might be for the early JDM switch.

Does this work???

  1. Remove the regular wiper switch
  2. Install the new wiper switch and connect it to the stock harness
  3. Screw the AMP to the steering post with its SUB HARNESS
  4. Connect AMP harness to SWITCH
  5. Create the new connector (in Red circle of wiring diagram) and plug it in
    1. Connect Blue/Red (LR) wire to fuse box 'W' terminal
    2. Connect Black wire to an available earth
    3. Connect Yellow wire to the original stock SWITCH connector Y wire

Other Datsuns

Some B310s had intermittent wipers. The B310 motor is wired the same. The amplifier box is similar but has a sixth terminal for fast-intermittent. But you could use it for the 1200 (using either slow-intermittent or fast-intermittent).

Aftermarket

Hella Australia make a universal intermittant wiper switch. Unlike the 1200 intermittent option, it doesn't have set speeds you just turn the dial and the speed changes (variable-speed intermittent).
