Thank u for replying where does it pick up the speed from. And frost when you tune can you get rid of the abs light no problems just once the 9 inch is in there I order with out abs. Thanks again for you two replying

No, the ABS light comes from the BCM, not the PCM. You either have to live with it, or remove the light itself from the dash.

I can fix the speedo as part of mail order tuning if you would like. Here is the link: http://www.tunedbyfrost.com/services2.htm

Let me know if you have any questions.
