Installation instructions - Here a quick overview of the most popular engines. The original installation instructions are more detailed and easy to follow through.

Installation instruction for a Pumpe Düse Power Box - First remove the sound-absorbing cover. The original connector is located right at the side of the motor block. (arrow)

Just plug the Power Box connectors in between the original connection and connect the red and black cable with the battery. (red for plus/black for minus). Done!


Installation instruction for all 1.9l TDi's - Basically you can divide the newer TDi's by lengthwise and crosswise designed motor blocks. (most of the time lengthwise 8pin version, crosswise 10pin version). First remove the sound-absorbing cover, then plug the Power Box connector right in between the original connection (right in front of the motor block down to the right, arrow) and connect the single cable with the MAF (air flow) sensor (arrow). 

If the MAF sensor has 5 connections, connect with number 5, if it has 6 connect with number 6.


Installation instruction for all Mercedes CDI, BMW d and all JTD common rail engines - With those Power Boxes you have to find the ECU's (control units). At Mercedes and BMW engines for example the ECU is located in the engine room, close to the rider side.

At Alfa Romeo and Fiat engines the ECU is located at the feet of the rider.

To install the Power Box you have to plug 2 connectors in between the ECU and the original connectors, then connect one cable to the ground or permanent plus, done!
