tac module

You need another digit in the TACM part number, should be 8 digits.

The 03-04 Escalade 5.3 or 6.0 shows 12588923 for the TACM but that doesn't mean you have the wrong one as part numbers are updated over the years. I can possibly cross reference the one you have to a newer number if you get the missing digit.
