My S10 originally had the 8625 PCM. To the best of my knowledge it will run $0D(same as 7427) and the 8625(93), 6395(94), and 7427(95) are interchangeable, but most people prefer the 7427. The ESC is not attached to the PCM. What your seeing attached is the DRAC module for the S10. The ESC is internal. Also one other thing that will be special about this PCM, if it's from a 4.3L, is it will require two knock sensors. Use the same ones from the 4.3L, but put one one each side for a V8, don't put in 4.3L locations they won't work well with a V8.
