The point here is simple: getting useful powertrain data into the cab should not turn into a wiring project. The Banks iDash 1.8 installs with a single OBD-II connection, fits any standard 2-1/16-inch (52mm) gauge mount, and wakes up automatically when it sees engine RPM. On first startup, you enter engine displacement so the gauge can handle its calculations correctly, then you are up and running. The result is a clean, universal install on any OBD-II vehicle, with the option to tuck the cable around trim for a neater finished look.
The video demonstrates how to install the iDash 1.8 on a vehicle using a GM L5P Duramax as the example platform, while noting that the basic process is the same for any OBD2-equipped vehicle. Installation begins with the OBD2 cable. The cable is inserted into the Gale mount, and then the iDash 1.8 is connected by plugging its 4-pin connector into the appropriate slot. Once connected, the gauge is placed into the Gale mount in the correct orientation, and the retaining screw is tightened to lock the unit in place securely.
After the gauge is assembled into the mount, the next step is to connect the OBD2 plug to the vehicle's diagnostic port. Port location varies by vehicle. On the L5P Duramax shown in the demonstration, the OBD2 port is located beneath the glovebox area, under the center console. With the connector plugged in, the physical installation is functionally complete and the system is ready to be mounted in its final viewing position.
The recommended mounting location is on the windshield, typically near the A-pillar for good visibility and convenient access. To install it there, the suction cup is pressed firmly against the glass and the locking tab is pulled to secure the mount. Once locked, the mount is held firmly in place and provides a stable platform for the iDash 1.8 during vehicle operation.
For a cleaner appearance, the cable can be rerouted around interior trim panels rather than left exposed. The video notes this as an optional step, but it improves the finished look of the installation. In the demonstration vehicle, the cable has been tucked around the trim pieces to create a neater, more integrated setup.
With the gauge mounted and connected, initial startup is straightforward. The iDash 1.8 powers up automatically when the vehicle is started. It looks for the engine RPM signal and uses that signal to wake itself up, so no separate power switch or manual startup procedure is required.
Because this is the first time the unit is being started, the gauge prompts for engine displacement. That value is required because the iDash 1.8 uses engine size for certain calculations. In the example shown, the installer enters the displacement in liters. Using the select button, the menu is set to liters, and holding the button allows faster scrolling through the available values.
For the GM L5P Duramax used in the demonstration, the correct engine displacement entered is 6.6 liters. After selecting that value, pressing the back button returns the display to the main gauge menu. At that point, the iDash 1.8 is fully initialized and running, and the screen shown is the standard view presented when the unit is first powered up after installation.
