CACHÉ KIT110 Bundle with Automotive Stereo Set up Equipment for Pontiac Bonneville 2000 – 2005 in Sprint Mounting Equipment, Wire Harness for Double Din or Single Din Radio Receivers (4 Merchandise)

Great fit into ‘05 SE. A FEW THINGS TO NOTE!
I’ll update this review in a day or two once the radio is in the car, but I already know the harness fits perfectly into my ‘05 Bonneville SE radio plug (the antenna wire works too). It won’t go in the wrong way, either. I’m running an ATOTO F7 XE Radio with a backup camera I plan on adding later when I feel like routing the wires through the whole car. The connections are clearly marked and detailed enough (i.e. Green+Black= LeftRearNegative). Has six brown wires for “TEL MUTE” that are too dated for my radio, so I cut them short. Also has three GND connections for some reason… I conjoined them all using one wire to the ATOTO harness; should be fine.NOTE: This harness is for non-amplified GM vehicles, so I cut the blue Amp cords short but left them long enough to be able to add an aftermarket amp / amp & sub later.NOTE 2: The Double DIN dash adapter kit isn’t a perfect fit into the Bonneville, but I plan on cutting slits into the left and right side of the radio holder in the actual vehicle. Might play around with my other options, though.— DAY 2Got the radio working. VERY IMPORTANT: Due to the DockandLock specifications of the stock radio, you are REQUIRED to route the red 12v ACC cable to the fuse box of your Bonneville! The factory radio does NOT carry an ignition signal on its own! I propped the radio against its compartment and ran the wire back to the fuse box under the backseats through the left side steering column / floor / door panels. I had to buy a Fuse Tap for this step. Plugged the tap into an existing 15A fuse plug (I HIGHLY suggest using the Airbag fuse as it is on ONLY while the car is ON (there is a fuse diagram on the underside of the fuse box cover). Don’t forget to plug 15A fuses into BOTH ports on the fuse tap. Point is, after about three hours, I was finally able to operate the new radio normally. The sound works well and no mess-ups thus far. The door/lights/seatbelt chimes no longer function, but who needs those? Also, the new harness doesn’t have OnStar support (but then again, who uses OnStar anymore?). The backup camera and the dash kit adapter assembly for the radio are the next steps.
