Help: Brake Bleed Sequence
Looked at the brake fluid and after 22K it is black. I plan on siphoning the reservoir with a turkey baster. Then refilling, bleeding each wheel position until I get clear fluid. If someone could tell me the correct sequence it would be appreciated.

Start at the wheel furthest from the master cylinder, then you should end up last with the drivers front tire.
You should also use a power bleeder, some are air powered, and even hand pump up units.
Don't pedal pump to bleed the brakes.

The brakes are divided into 2 circuits for safety - the LR/RF, and RR/LF. And that's the way the service manual says to bleed them.
However, if you aren't going to use a Tech 2 to open the ABS valves and circulate fluid through that circuit, then I think the standard technique like C4 Racer mentions will work fine.
That's what I do - RR, LR, RF, LF, and if works great.
I have a motive power bleeder and it makes it a very easy one-man job.

You've gotten some good advice. Here's a couple links that may help...

I'm a big fan of my speed bleeders, easier than my vacuum one-man bleeder.
I go both rears and then both fronts (as I jack up the rear then front on the cradles) to put in new fluid before track events, never using a tech II, and it works great. You end up getting new fluid in the calipers no matter where you start in my experience.
I think the order of bleeding matters mostly if you get air in the system. Don't do that. Keep an eye on your master fluid level.

Install them, crack them open one at a time, run a clear hose to a bottle or can, use your foot to bleed until it's clear coming out for each wheel. Super easy.
Just be sure to keep your eye on your master. Don't run it dry or you'll get air in the system which is a pain.

The thing I do not like about pressure bleeders is that you have to pressurize the master cylinder reservoir, and if you get a leak, you can have brake fluid everywhere.
I would just use the old manual method, and bleed the wheels one at a time by having an assistant push the brake pedal down while you open and close the bleeder valves.
The bleeding sequence is RR=>LF=>LR=>RF
