Old version of manual
First of all locate fuse box in the cabin right on the passengers side. You should find wires marked as 3701C (blue), 3700C (yellow), 1198 (red) and white wire (next to red wire, without code number). Usually these wires are located in the left side, upper corner of the fuse box. You’ll see grey plug (normally you should find there red wire (1198) and white wire (next to red wire) mentioned before. Third plug under the first one should have blue wire (3701C) and yellow wire (3700C).

Each AdBlue Emulator V4 NOx has six wires, but for the proper connection on DAF LF (Grundfos) truck we need only four wires (AdBlue Emulator V4 NOx is universal and supports various trucks made by various manufacturers and extra wires that we will not use on DAF LF trucks are necessary only on other trucks). You must connect AdBlue Emulator V4 NOx emulator in such configuration (unused wires of emulator should be isolated).

When you connect emulator to proper wires of the truck you need to disconnect NOx sensor and AdBlue sensor of the truck. Cut four wires of the NOx sensor and then cut eight wires of AdBlue sensor. You can just disconnect power source of NOx sensor (pin 1 and pin 4), also you can just disconnect power of AdBlue dosing module (look for the yellow arrow on the image). When you do all steps described in this manual your DAF LF (Grundfos) should work normally without any additional exhaust smoke or engine power reduction. Please Keep in mind that you must purchase emulator preprogrammed for DAF LF, if it will be programmed for DAF XF it won’t work. If you have AdBlue Emulator V4 programmer device you can check AdBlue emulator program before installation (do not connect programmer to emulator while it is connected to the truck it can damage emulator, truck ECU and even itself).
