Before you start
- Read every step in full before beginning any wiring or drilling.
- Disconnect the battery negative terminal before making any connections.
- Two-person job recommended when feeding the loom through the headlining and A-pillar.
- Always verify door-sensor polarity (Section 2.4) with a multimeter before connecting — incorrect polarity will not trigger the warning lights correctly.

Signage & lights
1.1 — Front signage & lights
- Align the SCHOOL BUS sign centrally above the windscreen – typically it is 360mm from rail to edge of sign. Confirm that the sign is 360mm from the sign to the rail from both sides.
- Measure 10mm from the bottom of the sign to the top of the windscreen (or 2mm from glass on buses with antenna on top)
- Place the SB008 lights on either side of the SCHOOL BUS sign and visually confirm that they are level with the road.
- Drill 4x 3mm holes for mounting and a 6mm hole for the cable
- Attach the SB008 lights with pop rivets or stainless steel screws, applying UV stabilised silicone
- Run the cables inside the bus and crimp the 2-pin connectors on the ends.
1.2 — Rear signage & rear lights
- Open the tailgate, remove the trim and loosen the flexible rubber boot at the top of the passenger side of the tailgate.
- Close the tailgate and stick the 40km sign centrally above the rear glass. Cut the "WHEN LIGHTS FLASH" in half and stick either side of the 40km sign. see Fig. 3 for placement
- Place the black light bracket on either side of the sign, drill 2 holes for mounting and one 6mm hole for the cable.
- Run the cables inside the bus, they will then be accessible via the open trim. Apply UV resistant silicone.
- Crimp the 2-pin connectors to each light cable

Wiring
2.1 — Front to back
- Remove the plastic trim around the glove box and A-pillar moulding.
- Run the loom from the top of the A-pillar to the rear of the bus through the headlining or air vents. This is typically the point where the loom is cut and rejoined with the 3-pin connectors.
- At the front of the bus, run the cables through the headlining and crimp with supplied 2-pin plugs.
- At the rear of the bus, push the cable through the rubber boot on the tailgate (passenger side). Using cable lube will ease the process.
- Crimp the loom with the supplied 2-pin plugs and connect the the lights
2.2 — Switch
- Using an 18–20mm hole saw, cut a hole in the dash and insert the supplied switch. See Fig 4
- Connect the switch to the grey connector
2.3 — Glove box area
- Below the glove box, connect the black GND wire to ground.
- One power option is below the glove box. Connect the red +V wire to a fuse in the fuse box. Check with a multimeter for ignition power.
- Connect the supplied 6-way connector to the switching box.
2.4 — Door sensor
Suggested: connect the brown door sensor wire to the red wire (pin 13 on the white connector in the A-pillar). An extension of the brown wire may be required. The red wire on pin 13 should give GND when the door is open. Confirm that this is correct BEFORE connecting the wires. See Fig 5
