Are you looking to enhance your vehicle’s monitoring capabilities with advanced gauges? The Aeroforce Tech Interceptor Obd2 Scan Gauges are a popular choice for car enthusiasts seeking real-time data and performance insights. These gauges plug directly into your OBD2 port, offering a wealth of information from your car’s computer. However, sometimes a direct OBD2 connection isn’t enough, and a power wire is required for consistent operation. This guide will walk you through the simple process of wiring your Aeroforce Interceptor gauge, ensuring you get accurate readings and optimal performance.
Sometimes, just plugging your Aeroforce gauge into the OBD2 port might not fully power it, especially in certain vehicle models. A common issue, particularly noted in some older Grand Prix models, is the need for an additional power wire. To determine if your vehicle requires this extra step, simply plug the OBD2 connector of your Aeroforce gauge into your car’s OBD2 port and turn on the ignition. If the gauge powers up, turn off the car, remove the key, re-insert the key, and turn the ignition back on. If the Aeroforce gauge doesn’t display correctly – often showing a blank screen with red indicator lights – you’ll need to proceed with wiring the power wire as described below.
Step-by-Step Guide to Wiring Aeroforce Gauges
Here’s a straightforward guide to properly wire your Aeroforce Tech Interceptor OBD2 scan gauges, ensuring a stable power supply and reliable readings.
Step 1: Remove the Jumper
Before starting the wiring process, locate the jumper on the back of your Aeroforce gauge. This small red or black component needs to be removed. This step is crucial for preparing the gauge for the external power source.
Step 2: Gather Your Wiring Components
You’ll need a few essential items for this installation: a wire terminal or splice connector and a length of 16-gauge wire. While slightly larger gauge wire is acceptable, ensure you don’t use anything thinner than 18-gauge to guarantee proper power delivery and prevent any potential issues.
Step 3: Route the OBD2 Wire
Begin routing the gray OBD2 wire that comes with your Aeroforce gauge. Starting from the floorboard area, carefully feed the wire upwards along the side panel of your vehicle’s interior. Continue routing it up through the side of the dashboard, reaching the location where your gauge pod is installed. Pass the end of the OBD2 wire (the end that connects to the gauge) through the designated hole in your gauge pod, ready to be plugged into the Aeroforce gauge. Important: Do not connect the OBD2 plug to your car’s OBD2 port at this stage.
Step 4: Connect the Power Wire
Now, take the red power wire included with your Aeroforce gauge. Splice your 16-gauge extension wire to this red power wire. Similar to the OBD2 wire, route this power wire through the hole in the gauge pod first. Connect this power wire to the Aeroforce gauge. Instead of routing downwards like the OBD2 wire, direct the power wire downwards towards the floorboard area and then towards the glove box.
Step 5: Fuse Box Connection with Add-A-Circuit
Your target is the fuse box, typically located within the glove compartment area. Route the power wire towards the glove box and look for a space underneath it, near the fuses, where you can bring the wire up. Pull the wire up, providing yourself enough slack to work comfortably on the connection to a Littlefuse Add-A-Circuit. These Add-A-Circuits, costing around $8-$10 at auto parts stores like Autozone, are highly recommended as they prevent the need to cut or splice into your vehicle’s factory wiring.
To use the Add-A-Circuit, insert the power wire into the terminal and crimp it securely. Identify a suitable ignition-related fuse in your fuse box – fuses like PGM, Mall PGM, or IGN are good candidates. Remove your chosen fuse and insert it into the designated slot on the Add-A-Circuit. Then, add a new 10A fuse into the additional slot on the Add-A-Circuit. You should now have two fuses in the Add-A-Circuit. Finally, plug the Add-A-Circuit assembly back into the fuse block location where you initially removed the fuse.
Step 6: Final Connections and Testing
With the power wire correctly connected to the fuse box, you can now connect the OBD2 plug to your vehicle’s OBD2 port.
Start your vehicle and observe your Aeroforce Tech Interceptor OBD2 scan gauge come to life! If everything is wired correctly, the gauge should power up and begin displaying vehicle data.
Remember to consult the official Aeroforce Interceptor gauge instructions for detailed startup procedures and programming guidelines to fully utilize the features of your new gauges. Enjoy the enhanced vehicle monitoring provided by your Aeroforce Tech Interceptor OBD2 scan gauges!
