You don't need the other side of the relay. You could of put the other side of the switch to pin 3 instead of pin 6, but I wasn't sure how far you had gone based on the diagram.
I just thought it was easier to say forget the wires to the LED.
Sorry, didn't mean to sound condescending or anything.

I see - I thought I read somewhere above that if you aren't using the LED you'll only use "one side of the relay". But, I must have misinterpreted that. So, the orange wire will still go to BOTH Relay pin 5 and Relay pin 6. Pin 6 will also have one side of the switch. Pin 8 will be to the white w/ black stripe.

I haven't started yet bc I wanted to make 100% certain of what I was doing. I'm going to wire things as follows:
1. Cut the blue wire.
2. Relay Pin 1 = blue wire from loom
3. Relay Pin 5 = blue wire from Nav unit
4. Relay Pin 3 = tapped orange wire & one side of the switch
5. Relay pin 7 = other side of the switch
6. Relay pin 8 = ground (from whatever source)
Sorry, I'm really good at actually implementing this stuff if I have a very detailed DIY... I just suck at figuring the steps out myself.

Good luck. It seems that you are on the right track.

Do you have a specific concern?
Therefore, I wonder if you have a specific question or concern I can help you with in order that you will feel confident in this modification.

Simple, but will it work?
Hey all,
I am really interested in doing this mod for my rx400h. I would love to have the ability to turn the backup camera on at will. I am not all that great at wiring, but I am ok. My main question is, couldn’t I run a wire from a toggle switch to the blue wire (soldering the blue wire and the wire from the switch together), with a 12v supply (probably from a cigarette lighter) running to the switch? The idea being that when the switch is on the camera will come on as a result of the 12v power going to the blue wire. The camera will still work when the vehicle goes into reverse because the blue wire is soldered together along with the switch wire. I loaded a crude picture of what I am talking about. Will this work? Any thoughts?
Thanks,
Bill

I'm afraid not Bill.
When you switch across the switch, it will short the positive and negative and blow your boots off.
It is also a good idea to break into the blue wire rather than connect to it as you would be feeding the 12v back into the system, not just the screen to switch into the camera mode.
What you need to do is apply 12v to the blue wire at the screen but stop it going back into the vehicle wiring. You need a changeover switch at least to do this. It has 3 points on. One is common to the other two, depending which way it is switched.
Switch in one way, it is as normal Lex wired. The other way applies 12v the blue wire on the screen side, but disconnects the blue within the rest of the vehicle wiring.
You could pick up the 12v from the cig lighter, but as others have pointed out, the orange which is already at the back of the unit has a 12v supply anyway - just tap off this.

geooffers,
Thank you so much for the post. So the key to a simple switch mod is using a SPDT switch (http://en.wikipedia.org/wiki/Switch). Would a switch like this work?

And the idea is that with the three connections on the switch the diagram would look like this?
