We’ve offered connector kits for the Bosch iBooster Gen-1 for a while but for those who are not interested in crimping pins and building the harness themselves, or simply looking to save time during the install, we now offer a preassembled universal wire harness. Both the iBooster connector and Pedal Travel Sensor connectors are fully assembled and just need to be plugged in. Then there are a few generously long labeled loose wires that you can cut to the length you need and appropriately connect to your vehicle.

Bosch iBooster Gen-1 Universal Wire Harness Loose Wires:

4.00 mm² – Red (FLRYW) – Always Hot Power (recommended to use a 40A Fuse) – 3m long
1.50 mm² – Red (FLRYW) – Always Hot Power (recommended to use a 5A Fuse) – 3m long
0.50 mm² – Green (FLRYW) – Ignition Switched Power (recommended to use a 5A Fuse) – 3m long
4.00 mm² – Black (FLRYW) – Chassis Ground – 1m long

The Bosch iBooster is an electromechanical brake booster (rather than vacuum assisted) primarily found on Electric Vehicles such as Tesla, but can also be found on other vehicles including ones with an Internal Combustion Engine.

The iBooster is able to run in a fail-safe standalone mode with no other connections or communication to additional components needed besides voltage supply and chassis ground as the iBooster has an internal Pedal Travel Sensor that is externally wired to the iBooster ECU. The information from the Pedal Travel Sensor is used by the iBooster ECU to drive the electric motor which provides additional force towards the Master Cylinder.

Therefore the iBooster is an ideal component for many applications such as electric vehicle conversions (rather than using a vacuum pump), classic cars / muscle cars / hot rods (typically with manual brakes), limited vacuum pressure (such as diesel or turbo engines), or clearance issues of engine swaps (like the BMW E30 with a S54 engine).

Notes:

– Please allow extra processing time if these wire harnesses are on back order as they will be built per order. If we see an increase in demand for these will we try to keep more in stock.

– There are two versions of the Bosch iBooster; Gen-1 and Gen-2. Be sure to order the correct wire harness based on the style of Pedal Travel Sensor Connector.

– All items within this wire harness are genuine items sourced from authorized distributors.
