Hi, I am installing my hands-free speakerphone kit for my cell phone in my RX8. Found an acceptable mounting place, but I need to tap into +12VDC (always hot), +12VDC (hot when accessories are on), and a good ground (12VDC return). All three of these wires are currently located in the area of the interior fuse box. Tap connectors would be fine if I knew which wires to tap into.

 

OK, answered my own question. I located the power and ground wires behind the fuse panel in the cockpit (with a little help from a DVM) and tapped into them. There's VERY little room in which to work there!. But now my hands-free speakerphone kit works as it ought and I also reconnected my accessory power socket so that it is hot all the time -- much better for running a laptop.
