Icaad, I didn't see what year your 3rd Gen was. I mounted my DiPrico's in the cubby and love it. I tapped into the back of the dimmer switch as pwer instructions I received from Geno's. BTW, When I received my DiPrico's I was a little disappointed with the installation instructions. I telephoned Geno's and spoke to someone (Sorry, don't remember who) and relayed my concern. Geno's sent me a detailed installation guide that made the job a breeze. Especially with hooking lighting to the dimmer wire. It was exactly where they said it would be. Huge thanks to Geno's!!!!! The only thing I'm not jazzed with is the lighting of the DiPrico's in twilight conditions. Very difficult to read but daylight and hours of darkness the gauges are great.
