Using this SMY gauge pod is a breeze. First, locate the OEM mounting points in your 2002 - 2007 Subaru WRX or STI. The top has 2 screw mounting holes and the bottom has 2 tabs to help you secure it properly. If your car has stock mesh or rubber covering the steering column gap, you can reuse them with the OEM mounts on the pod. When inserting gauges, remember they can be up to 2.5 inches deep, and you can remove the brackets from the gauges as they aren't necessary for this pod. As for maintenance, just use a soft, dry cloth to clean the pod. Avoid using harsh chemicals that could damage the OEM - like color and texture. Also, keep in mind that this product is only for left - hand drive cars, so make sure your vehicle meets this requirement before installation.
