If no constant power supply is available at the dome light, power and ground can be provided by the fuse box
Use an add-a-fuse adapter to get power from the fuse box & ring connector to get vehicle ground where available
IMPORTANT: The fuse box adapter and fuses are not part of the delivery package by Bosch and must be acquired by the MSP.
Required tools (may be different depending on your vehicle):
Pliers
Prying tool
Insulation tape
Crimping tool
Add-a-fuse adapter & fuse which fit your vehicle type
Ring connector
Preparations:
Acquire fuse box adapter & fuses (Bosch recommends Eaton brand)
Acquire ring connector
Cut off the plugs at the very end of the long cable
Crimp the power cable of the device into the fuse box adapter
Crimp a ring connector to the ground cable of the device
IMPORTANT: Each fuse box is different. Make sure to examine your vehicle‘s fuse box prior to acquiring the fuse box adapter & fuses; in order to ensure the correct size is acquired.
IMPORTANT: Please make sure that the right location in the fuse box is used to provide power to the device. More detail on identifying this can be found on the next page.
Identifying the right fuse location to pull power from:
Using a multimeter set to check DC voltage, probe ground from the vehicle where available, and probe power from the top of the desired fuse. A suitable location will have constant 12V, and the fuse rating must be higher than or equal to the new fuse you have purchased for the device.
Remove the fuse using needle nose pliers, and then probe power from each side of the open slot. The side with 12V will be the load side, and the side with 0V will be the draw side (see diagram on the right).
When inserting the fuse adaptor, take care to insert in the orientation described to the right. In other words, the load side as described in the diagram must correspond to the side of the fuse slot which provides constant 12V. This will ensure that the power will cut if the fuse blows.
IMPORTANT: Check which vehicle functions go to which fuse location (diagram is usually located on the plastic cover for the fusebox). Care must be taken to ensure that power for this device is not pulled from safety-related vehicle functions, such as: airbags, anti-lock brake systems, traction control, and collision prevention systems.
After the preparations are done:
Route the long cable of the wire harness from the specified device location to the fuse box.
This is usually done by routing up the A-pillar and over the headliner − Attach the long cable to the short cable
Identify a suitable ground location and connect the ring connector accordingly
Identify the correct location to get power from the fuse box (see previous page) and plug in the fuse box adapter
IMPORTANT: Please make sure, that the cable in the engine compartment is secured by insulation tape.
IMPORTANT: Please make sure, that the cable routed over the apillar does not interfere with the side airbag system.
