Hi Entwood, here is my procedure to change the ABS ECU. I put it in a new thread hoping I can find it again if needed.
I. Unclip fuseholders above battery; remove battery.
2. Drain power steering fluid reservoir, remove reservoir. Try not to spill fluid on ABS ECU.
3. Release ABS metal hoses from clips on bulkhead behind ABS unit.
4. Unplug ABS ECU multiplug by pulling purple locking clip towards wing while wiggling connector. See picture.

6. Grasp ECU assembly firmly, raise it a bit to release it, then tilt front upwards to give access to ECU retaining screws. Support raised end.

Replacement is reverse of removal. To replace multiplug start with purple locking strip fully out, then offer plug into socket, wiggle plug as you slide in locking strip. You can see in pics guides on outside of plug. Refill power steering fluid reservoir with new fluid. No need to bleed anything, hoses were not removed. On testing ABS light will go out after driving a short distance.
