You must have a short in that circuit. The IOD circuit usually powers items like radio memory IIRC. Pull the IOD fuse and test each side of the fuse socket with the key in the ON position. One side should not have voltage. If it does then you have some sort of voltage feeding back
to the fuse as well as voltage feeding to the fuse. What (re)wiring did you do recently?
