2005 Brake fluid change question

After reading the instructions for changing brake fluid on the Integral ABS system, I have 2 questions.

1) My '05 doesn't have a split rear reservoir. Do the front and rear calipers both feed from that single one?

2) While flushing the fluid out through the calipers using the power from the pump, where do you refill - the rear fluid reservoir or the ABS unit?

The reservoirs for the Wheel Circuits are on top of the brake modulator itself located on the left side of the LT (under the seat- just forward of modulator bleed points) and yes there are two reservoirs. -Modulator Reservoir Inboard---bleedpoints at front calipers
-Modulator Reservoir Outboard---bleedpoints at rear caliper
Yes the modulator controls the Wheel Circuits so bike has to be on and fluid will move quickly the more the levers are depressed.

Thanks Bob.

So does that mean I have to have a way to refill the modulator or will the fluid from the reservoir flow through?

Bob, I think we need one of those neat Martini glass funnels that Zeiler is talking about.

Fluid does not flow from/thru one reservoir to another in any circumstance. Each reservoir (there are 4) has to be kept filled as you bleed. Jzeiler and others have devised several ways to make it easy or just keep your eye on the reservoirs as you bleed them to make sure the level doesn't get too low. A flashlight pointed at/in the reservoir helps you see better.
