Start/Stop Functionality Installation Guidelines 1. Locate the vehicle battery and relay contactor into the vehicle. 2. From the main harness, locate the battery wires for BAT, NBAT and ACC1. These wires need to be spliced, and also a fuse holder added to the BAT wire. 3. Connect the positive (50 mm 2 red wire) with the 150A fuse to the positive of the battery. 4. Connect the negative (50 mm 2 black wire) to a ground post as close as possible to the negative terminal of the battery. 5. Connect the BAT wire to the positive terminal of the battery. This wire is connected to K35, and from there needs to be connected to the Vehicle ECU as follows:
Connect BAT4 wire from K35 to pin 85 of the Relay Connect wire SPST2 from K35 to pin 86 of Relay Connect pins 87 and 30 to your vehicle ECU (pin 87a is not used) Note: The way that these pins are connected to the vehicle ECU depends on whether a high-side or a low-side input to the vehicle ECU is required to manage the start stop inhibition. Please consult your vehicle documentation for this information. 6. Connect the NBAT wire to the negative terminal of the secondary battery . This reference signal allows the gateway to accurately measure the battery voltage without voltage drop. Important: Please ensure to connect the NBAT wire to ground.
The unit will still operate if you fail to do so, however, it will not operate correctly and may be hard to troubleshoot at a later stage. See diagram below. 7. Connect the ACC1 to the ignition switch. (Typically known as K15 output). 28 TK 56881-18-IM-EN Description: TK Service Parts Number: 7. Seal Cable Yellow - Outside Diameter 1.8-2.4mm 414625 8.
