Tools and Materials Needed

• #1 Used Late Style Tachometer (0005425916)
• Screwdrivers (flathead and Phillips) 
• Socket wrench set – Pliers 
• Wire cutters/strippers 
• Electrical tape 
• Mounting brackets and hardware (if not included with the tachometer) 
• Instruction manual for the tachometer
• Service manual for the Mercedes 280SL 

Preparation & Installation

1. Safety First: Ensure the vehicle is parked on a flat surface, and the parking brake is engaged. Disconnect the negative terminal of the battery to prevent any electrical accidents. This is a step that should be taken for replacement of any and all Mercedes 280SL parts.
2. Locate the Installation Area: The tachometer is typically installed near the dashboard or in a location where it can easily be viewed and accessed by the driver. Refer to the tachometer instruction manual and the Mercedes 280 SL service manual for the recommended installation area. 
3. Remove Necessary Panels: Depending on the location, you may need to remove some interior panels to access the mounting area and electrical connections. Use the appropriate screwdrivers and gently pry off the panels, taking care not to damage any clips or fasteners. 
4. Install the Mounting Bracket: If your tachometer came with a mounting bracket, install it in the designated location. Use the provided screws and a socket wrench to secure the bracket firmly. Ensure it is level and stable to avoid any vibrations while driving. 
5. Attach the Tachometer: Once the bracket is securely in place, attach the tachometer to the bracket. Follow the manufacturer’s instructions for proper alignment and secure the tachometer using the screws or clips provided. Make sure it is tightly fastened to avoid any movement. 
6. Identify the Wiring Connections: Refer to the #1 Used Late Style Tachometer (0005425916) instruction manual to identify the wiring connections needed. Typically, you will need to connect power, ground, and signal wires. This applies to Mercedes 280 SL parts that require wiring for the sending of signals or power.
7. Connect the Power Wire: Locate a suitable power source in your Mercedes 280 SL. This could be an accessory power source that is only active when the ignition is on. Use a wire stripper to strip a small section of the power wire, and then connect it to the #1 Used Late Style Tachometer’s (0005425916) power wire using a suitable connector or electrical tape. 
8. Ground the Tachometer: Find a suitable grounding point near the installation area. This could be a metal part of the vehicle’s chassis. Attach the ground wire from the tachometer to this point using a screw and ring terminal for a secure connection. 
9. Connect the Signal Wire: The signal wire typically connects to the vehicle’s speedometer or tachometer signal. Refer to the service manual for your Mercedes 280 SL to locate this wire. Use a wire tap connector to splice into the signal wire and connect it to the tachometer’s signal input.
10. Reconnect the Battery: Once all the wiring connections are made, reconnect the negative terminal of the battery. 
11. Test the Tachometer: Turn on the ignition and test the Tachometer to ensure it is receiving power and displaying the correct information. Check all functions as described in the tachometer instruction manual. No matter what Mercedes 280SL parts you replace or repair, you should always test them before you take your vehicle back on the road.
12. Secure and Reassemble: If everything is working correctly, secure any loose wires with zip ties and reassemble any interior panels that were removed during the installation process. 
13. Final Adjustments: Make any necessary adjustments to the tachometer position or settings to ensure it is easily readable and functioning properly while driving.
