TSL subaru

Hi all im faily new to the subaru, i was wondering if anyone out there can help me. I want to change my speedo clocks. The ones i have at the moment are wrx 2002 blob eye clocks with the speedo in the centre and revs on the right. I purchased some with the rev counter in the centre now from 2006 model. The problem im having is when there plugged in everything works fine except the handbrake light and ABS light stay on. I change the clocks back to the originals and they work fine. Is there a slight wiring difference or are the wiring to the plugs different. Can anyone assist me with my problem. Thanks.
