How do you attach dummy baits (swimsuits) to an Alabama Rig. My state has a 3 hook limit so I need to know what I should do to attack the remaining two baits to the rig.

You can use a hitchiker to put your bait on.Or you can use a jig head and cut off the hook!

You can get hitchikers at Bass Pro And Tackle Warehouse.

Use the Owner Springs on the dummy bait arms and screw the plastic on the nose -

Or just use a generic willow blade.

we have the same restriction in California.   I just attach the dummy plastic baits directly to the snap swivel on the A-Rig...no need to buy anything else

Either way above or you can use the dummy heads by Picasso which I use often being from California as well.  Seems to help balance the rig a little better when the heads are all about the same weight.
