Delta APRU Vehicle Mount Installation: Step-by-Step Guide

Quick Answer

Install the Delta APRU Vehicle Mount and Hardwire Cable by first choosing a secure mounting location, then routing the hardwire cable to your vehicle's power source, and finally securing the mount and connecting the unit.

Installation Steps

1. Step 1: Disconnect the Vehicle Battery: Before any electrical work, disconnect the negative terminal of your vehicle's battery to prevent short circuits or accidental activation. Use a wrench to loosen the terminal clamp and remove the cable. Double-check that the battery is disconnected before proceeding to avoid electrical shock or damage.
2. Step 2: Mount the Bracket: Position the Delta APRU vehicle mount bracket in your chosen location. Use the included hardware (screws, bolts, or clamps) to secure it to a solid surface. Ensure the bracket is level and tight, as a loose mount can cause the unit to shift during travel. Test the bracket's stability by applying gentle pressure—if it moves, tighten or reposition it before moving on.
3. Step 3: Route the Hardwire Cable: Run the hardwire cable from the mount location to your vehicle's fuse box or a constant 12V power source. Hide the cable under trim panels or carpet using a plastic trim tool to avoid pinching or fraying. Leave enough slack at both ends for connections. Avoid routing the cable near moving parts (e.g., pedals, seat rails) or heat sources (e.g., exhaust components) to prevent damage.
4. Step 4: Connect to Power: Strip the cable ends and connect the positive (red) wire to a fused 12V source, and the negative (black) wire to a clean chassis ground. Use a fuse tap or inline fuse holder rated for the Delta APRU's current draw (refer to your unit's specs). Secure all connections with crimp connectors or solder and heat shrink. Always install a fuse within 12 inches of the power source to protect the cable and device from overload.
5. Step 5: Attach the Delta APRU Unit: Slide the Delta APRU unit onto the mounted bracket until it clicks or locks into place. Connect the hardwire cable's connector to the unit's power port. Ensure the cable is not taut and has a small loop for strain relief. Verify that the unit is securely locked and the cable is not pulling on the connector—this prevents accidental disconnection.
6. Step 6: Test the Installation: Reconnect the vehicle battery. Turn the ignition on (if required) and power up the Delta APRU. Check that the unit powers on, the display or indicators function, and that the mount remains stable during a short test drive over bumps or turns. If the unit does not power on, check all connections, fuses, and the ground point. A multimeter can help confirm voltage at the cable end.
