I would like to tap into accessory power in the trunk(when key is in 12v comes on). How do I get that? Thanks alot for your help!

Remove the trunk lining, there is the fuse box on the driver side. Remove the box cover, there is an empty socket for the relay. Use your ohm meter find out the 12V pin. I used this for my NavTool, It's much easier than tap into the wire bundle of the Nav unit. Sorry, I don't have the picture to show.

<br /><br />I tried those same spots in the trunk fuse box using an "add-a-fuse" for my amplifier but I believe they are constantly "hot;" correct? This might lead to a battery drain depending on what you might be powering. Just a thought from my experience. Please correct me if I'm wrong.

Thanks a lot guys! I finally found the acc power in the grey wire on the Pioneer unit and managed to insert a wire in the slot to tap it. Now I just completed my installation of backup cam with Naviks. It was not easy, but probably well worth it.

You are correct. I thought the pin I used is "key on", turned out, it's not. I ended up spliced to the DVD 18 pin connector: pin 18 (gray wire).
