Its really simple to get the electronics, you stop the hood half way, and in the area where its sits when down, there is a cover, you peel this back and access all of the electronics.
The loom on the device has a male and female plug, you unplug the OEM one and plug it into the unit and then the other plug from the unit you plug back into the OEM control box. Then the is one power wire, which you tap into so it can power the hood, even with the ignition off, and one other wire to control the windows, to put back up after the closing or opening of the hood. It really is well thought out ..
Hope this helps
