Thanks for the info!! After replacing the EBCM, would the "Automated Bleed Procedure" (I think that's what it's called) need to be done with the Tech2? Would that procedure ned to be done after moving all the running gear to the new frame?

No, replacing the ebcm requires no fluid loss, so just replace the black module and your light should go out. It performs a selftest whenn you get to 5 or 6 mph. If you lost fluid, which i am guessing you did, swapping out the frame, then it would not hurt at all. If your pedal feels good you more than likely got all the air out, but its easy to do...

He's talking about the automated bleed procedure described in the manual that has to be done with a Tech II, not physically bleeding the air out of the lines.

No pics are necessary, i know exactly where its at, i just didn't know THAT was the ebcm. I thought the ebcm was somewhere up on the dash. I was confusing it with the bcm.

I think the schematics, if we need them are in the Factory Service Manual, which I have. Thanks for the offer, though.

Ohhhh, that's right, there's an electrical module that plugs into the actual ABS "Unit", right?

So what you're saying is, if we make sure the ground is good, and solid for that module, and the ABS light is still on, the EBCM is the culprit, right?
