I just did more research and turns out that for signals; I'm going to need resistors regardless.

The CANBUS bulbs are only for bulb out trips. I don't know if I have that in my car. I think it's only Audi/BMW/Mercedes that have the system where it tells you what lights are out.

I'm kinda thinking about Bob's Switchback idea thought I don't know if I want "white" lights where my signal is when it's off. I kinda like the combination of amber and white.
 
White could be cool.  We used to use chrome amber lights so they looked white when off. 
 
Nah these are different; switchbacks light up white when you don't have our turn signal active. When you flip your turn signal on they alternate between white and amber. So basically it's like having a set of fog lights.

Ecobob has a thread in how-to; go check it out.

Kinda against.
 
I would be careful just ordering bulbs from the numbers in the manual.  I have not been able to find anything that looks like the reverse bulb in my car.  Also, I know that when I went to do my bulbs in the interior, I could not use the same ones that Mike used in the how-to because they were too long.  Seems that between my build and Mike's Ford had switched the fixtures and the bulbs were different.  I would physically eyeball and measure the bulbs, so you get bulbs that will fit.
Lastly, when I tried to get LED's for just the taillight/stop bulb, I could not find one that would work correctly in the fixture...either they would not light or would light on full bright and not increase when the brake was applied.  One more thing, if you are going with LED in the front side marker light, although it calls for an amber bulb, it really should be a clear bulb because the marker itself is colored, and although I did get amber I believe clear would show a bit brighter...and these are a bear to get at to change the bulbs.  Just warning in advance.
 
Thanks maj;

I did verify those bulbs against the physical ones.

Bulbs be here next week. WOOT.
 
Just wanted to warn you, because I was really excited to change mine out and was pretty bummed when I had to return them and wait for the bulbs that fit. 
 
I am sending backup lights back tho or canceling before they ship.

Stock bulb is 264 lumens, these LED are only 100 lumens and highest they have are 194 lumens. I rather be able to see backing up.
 
Will be interested to see if the bulbs you ordered  will actually fit. I would like to change out some of mine also.
 
Not really because bulbs are different across platforms.

It helps, but you really do have to determine your proper bulbs by inspecting yours and measuring.

I'm still hunting for a 260+ lumens 921 base LED.

I found these looking for hipowered reverse lighting.  Work pretty good, but ultimately will probably go with a 15W HID kit as the final in-place product.

It's a big help but as I stated earlier, the fixtures in Mike's car are different from the fixtures in my car, and the interior bulbs do NOT fit in the fixtures in my car.  So you have to check to see which fixtures you have.  We are not sure if it was a change in production or just different fixtures, since Mike's build date is only 10 days after mine.
 
These are not the exact same ones I got.  Mine were from this seller

http://stores.ebay.com/3bspec

and description at the time was

3BSpec T15 921 912 906 Wedge LED 7W Q5 Cree Reverse Backup Bulbs White

Currently out of stock on this particular bulb.  Stated luminosity is 640.

I do not have a Gen4 SHO, but do have these installed in a '07 Edge.  I can measure them if you like.  The ones I have linked to above have stated measurements of

Size: 0.58" in diameter, and 1.80" long

and luminosity of 550.

Cree bulbs are very bright, generally the drawback is the amount of heat they produce, so generally better for well-ventilated or "short-duration" applications in tight spaces.
 
For backup light, that should be fine.

I wouldn't use them for anything else due to their lumens.

I bought these;

http://www.ebay.com/itm/2x-Super-Bright-Cree-High-Power-LED-Bulbs-For-Backup-Reverse-Lights-912-921-T15-/111074344444

They will not work for 2013 model -- my reverse lights are in my actual truck and they go into my housing at an angle--so when I put these in, they were basically pointing sideways. I need an actual 360 degree LED that puts out at least 300 lumens.

Here are some photos; if anyone can ACTUALLY use these and want them, let me know -- I'll sell them to you because seller won't take them back.
