PS-Rage, I've been following this thread for a while. I just want to say that my hat's off to you. You are truly a man amongst boys. I do have one complaint though; your install makes all the rest of ours look like it was done by a preschooler. Phenomenal work!

Another TS member (1tundradude) discovered in a Toyota document that the supply voltage for the back-up camera is supposed to be between 5 and 7 volts.
I've been running it at 12v for the last four months without any problems but if the spec says it should be lower this will no doubt extend the life of the device.
Luckily, this is an easy fix - all that is required is a Voltage Regulator.
I had on hand an NTE956 which is a generic version of an LM317. This is an adjustable voltage regulator whose output is set with a simple voltage divider:
A couple quick calculations finds my resistor values (R1 = 100ohms and R2 = 420ohms) and I can solder it together. Of course it is rare to find the exact values for resistors so I had to put a 220 and a 200 in series. All these parts should be available at Radio Shack, BTW.
Works like a charm. Regardless of my input voltage, the output remains steady at 6.76v:
A bit of heat shrink to protect the contacts:
And solder it in line:
As an added bonus, much of the video noise I previously had on the display has cleaned up. Musta been pushing the video amplifiers too hard.
I followed what I thought was the exact same procedure you showed above for the voltage regulator and resistors and my voltage is coming out to be approx. 4.63V....any suggestions? I used an LM317T (is that different from an LM317?), one 220-ohm and two 100-ohm resistors just as you have shown in the pics.
Thanks a bunch for the post.....it's been a great bunch of help to this point.
Justin, note that RAGE indicated he used a 100ohm(R1) and a 200/220ohm(R2) resistors = 520ohms, versus the 420 you indicated using. Add another 100 (or replace the 100 with a 200 - to mirror RAGE's install) and tell us the results.

I need to find the backup camera kit without the screen to hook it to my alpine IVA-W200... any ideas guys? Stealership wants too much and ebay kits are only with the screens I think.

If your looking for the cheapie special it ain't gonna happen my friend. Your talking about a "factory" option here. It does appear to be a quality camera though.
A couple quick calculations finds my resistor values (R1 = 100ohms and R2 = 420ohms) and I can solder it together. Of course it is rare to find the exact values for resistors so I had to put a 220 and a 200 in series. All these parts should be available at Radio Shack, BTW.
Do you have any idea what the power rating (W) is on those resistors? I have no idea how many amps the camera draws so I'm having a little difficulty in selecting resistors with the correct power rating. Thanks.

I recently installed the factory back up camera (w/o monitor) and am trying to hook it up to my DDX812 Kenwood. I cannot get a signal back from the camera. I used a voltage meter to test the connector under the back bumper and I am getting 12v (7v per Rages VM directions) to that plug. Should/Will the 12v tester light up if tested on the C+? Any ideas on why I am not getting a signal back from the camera? All of your information has been tremendously helpful. Thanks for posting your build.
This is the nicest instructional thread we have here on ts and rages tundra is the nicest equipped electronics wise. Although my needs aren't anywhere as demanding as his I have considered mounting a two way radio system as well as moving my gps antenna onto the roof.

These resistors are to set the reference for the VR. Any rating will do. I believe those were 1/4W
