hmm the problem is I can't find the right bleed procedure anywhere...

Hi, I have a 1990 Pontiac 6000 with the All Wheel Drive option that has the same sort of ABS set up you guys have.  Mine is the system IV, so it's a little different, but it's basically the same.  what happened was my Booster and pump failed.  It started to run the pump all the time and it was leaking brake fluid out of the booster.  now, when I say booster, I am NOT talking about a big vacuum operated thing... our cars don't have that.  I am talking about the high pressure part of the master cyl.  So what I did was I got an entire ABS set up from the junk yard out of a 1989 Cadillac.  The caddy pump was a little different, but not too much different, just the wiring.  I took my ABS all apart (not an easy task) and figured out exactly what was wrong with it.  I replaced my dead parts with working caddy parts put it all back together with new O-rings etc.  I bolted it on the car today, set everything up and the leaks stopped.  the pump ran initially about 15 seconds until the system was charged then it shut off.  I did not do a real good bleed job, and I was wondering if anyone knew the correct bleed procedure.  I bleed the front brakes as you would a conventional brake system, and it's not quite right...  the ABS light comes on, and the pump kicks on if I press the brake HARD or when I pump them.  the brake light is always on.  so do you guys think a good bleed is all I need?  Under normal braking, everything is fine, except my warning light ?Brake?
