Safety Precautions
Before starting the installation, ensure you are wearing safety glasses and working in a well-ventilated area. Disconnect the battery to prevent any electrical shorts during the installation process.
Step-by-Step Installation Guide
Step 1: Preparing Your Vehicle
Begin by parking your Audi S5 on a flat surface and ensuring the engine is cool. Open the hood and locate the battery. Disconnect the negative terminal to prevent any electrical issues.
Step 2: Locate the ECU
The ECU is typically located in the engine bay, near the firewall. Consult your vehicle’s manual for the exact location. Once found, carefully unplug the factory connectors from the ECU.

Take the JB4 ECU and connect it to the factory connectors you just unplugged. Make sure the connections are secure and the pins are aligned correctly. Refer to the JB4 installation manual for specific wiring instructions.
Step 4: Mounting the JB4 ECU
Find a suitable location to mount the JB4 ECU. It should be away from any heat sources and secured to prevent movement. Use zip ties to fasten the unit in place, ensuring it does not interfere with any moving parts.
Step 5: Reconnecting the Battery
Once the JB4 ECU is securely mounted, reconnect the negative terminal of the battery. Ensure all tools and loose items are removed from the engine bay.
Step 6: Initial Setup
Start your Audi S5 and let it idle for a few minutes. This allows the ECU to recognize the new piggyback unit. If you have an OBD-II scanner, you can check for any error codes at this point.
