LT1 files ?

[Len Sabatine]

     '95  has PWM capable Pump + Internal harness is different than '94,
      and SAE J1962 [ 16 pin ]  DLC in '95 F Bodys. No Prob for folks
      AWARE of mixing  incompatible HW - SW . The changes on the run
     can bite where it hurts, not to mention  a screen full of DTCs or History
     Code DTCs.
