: to get a better view of the whats behind you!
: $40 from amazon

Hello Club Lexus,
I posted a thread earlier asking about opinions for back up cameras, and I have figured it out and made my own back up camera with a monitor. Below outlines the steps that I took. Do this at your own risk, I am not responsible of anything that you do. This is an outline of my process and hope that you get ideas and do this yourself! This is done on a 2007 is250 awd, the wiring will vary from year to year. Use a multimeter to test voltages.
I wanted to outfit my non-nav is250 with a sleek hidden camera without making any extra holes.
The camera is mounted on the license plate light and the monitor is tucked away in the sunglasses compartment. like so...
On to the DIY
Sorry in advance, I took limited pictures of the install. Hope you can still follow along!
I ordered these following parts off of Amazon.com.
As an overview, the camera will have a signal connector (yellow) and a power connector (red); and will include an power wire connector and a yellow extension cable. The monitor has a signal connector (yellow), sound connector (white), and power connector (red); and will include a power wire connector. You will incorporate these wires into the cars harness! Both require 12V.
Start by removing the trunk felt protector/cover.
There are annoying clips on the rear that you can use by passing a zip tie through it and pulling them off.
Next locate the two nuts that go to the trunk opener. Remove them, and push the trunk opener into the trunk to make some room for the wires.
Take that back up camera and pass the video and power cord through the hole that you made.
Pull the cord through the hole (to your desired length). I am using 3M molding tape to secure the camera onto the reverse light. Thread your wires in and out of your harness to tuck it out of the way.
Tighten up the bolts for the trunk button.
Next located the plug that goes into the reverse light. You will wire the camera to the reverse light power, so when you put the car into reverse, the camera will turn on.
Unplug it and locate the wires. You will need to wire the power wire(red) and ground wire(black) to into the reverse wiring. In this case, for my car, the wiring was as so...
Red Power Wire --- Yellow Wire
Black Ground Wire --- White/Black Wire
After securing the wires together (I tied them together, you can also solder them), I wrapped them in electrical tape and tucked them away with the harness.
Find a TV/DVD player and test that everything is in working order. Plug the signal wire in to a monitor, and put the car into reverse....
Next you will have to plug in the extension and use this to route it to the front of the car, where the monitor will fit. Below shows where I put the wires.
Start in the trunk. Wire through the trunk cover, then down the gooseneck. When you are inside the trunk, you will have to pass it through the rear seat. This can be done by dropping the trunk liner and finding the grommet in the that existing wires are passed through. It will be easy to see when you remove the back seat (pull up on the seat bottom, remove 4x10mm bolts, pull up on seat back)
Once through the trunk, pass the wire under the seat siding (i forget the name now...). you can just lightly force/slide the wire under them.
Then to the front.... and remove the side cover and pass the wire up and to the A pillar.
Up the A pillar. Again, slide/force through the front of the headliner, until you get to the mirror. Pull lightly down on the headliner and then pass the yellow cord through it. Tuck/hide the wire under the headliner.
Remove the dome light, which is held on by two screws and two clips. Remove the screws. Pull hard down on the assembly and it will slide out.
You must then put a hole in the top of the sunglasses compartment. I used a box cutter to create this. This is for the wires of the monitor to pass through. As you can see, I put it on the lower corner of the compartment. Make the hole just big enough for the connector to fit through. Pass the connectors through and fit the monitor in the sunglasses compartment
I used the mirror power wires to power the monitor. This is done by wiring the monitor into the mirror/over head light harness. You can find this harness which is right behind the mirror in the headliner. It is taped to the headliner, and will require some fidgeting to get it out.
Once it is exposed, you will wire the monitor power wire to it, as shown below.
Red Power Wire --- Black Wire
Black Ground Wire --- White/Black Wire
Make sure that the signal wire from the camera, and the power wire (that you just wired) will be in the same spot!
Plug everything into one another, yellow->yellow, red->red. Put the console back into the car and screw it into place!
Push to Start. Put in "R". Look up and admire your handiwork.
