installed my eclipse 5435 nav system last week. i grounded the parking break wire so the unit always thought that the break is up, and i put the speed sensor lead on a switch so i could cut out the data to trick the unit into thinking i'm stopped if i want to change something on the go or let my passengers watch a movie.
using the phono out plugs (yellow red white) i wired up a 1/8"th jack for hooking up ipods and the sort, and three phono jacks for a video source such as a videocamera or something else temporary. to mount them, i just drilled into the factory option pop out modules. this way, if i want to resort to stock i can just replace the pop-outs and there is no drilling in my dash.i also split the video input and installed phono jacks under the dash for a more permanent installation if i add a video source down the road. below are pictures of the result. i'm putting my JDM HIDs in next week, pictures to come.
