Condition Description:

Pulled from a running vehicle and working when removed, unless noted otherwise in this listing. This is a used OEM GM (Delphi) engine computer from a running 2007 Chevrolet Silverado 1500 Classic 4x4, 146,000 miles. Label SERV. NO. 12602802, HDW NO. 12589162. Case shows dirt and light corrosion on the mounting screws; both connectors and pins are intact. The part shown in the images is the exact item we will ship you. GM computers carry the original vehicle's VIN and calibration: this unit will need to be programmed to your VIN with the correct calibration and a theft-deterrent relearn done with a dealer or capable scan tool before the engine will start and run correctly. Please match the service number on your original and review all images and ask questions before buying.

What this is: Original GM Delphi engine/powertrain control module for 2003-2007 GM full-size trucks and SUVs with the 4.8L, 5.3L or 6.0L gas V8 (not hybrid, not 4.3L), mounted at the left front under the battery.

  • 89017750 - Current GM service number that replaces 12602802 (discontinued by the manufacturer)
  • 12589162 - Hardware number on the label (HDW NO.)
  • 12606603 - Software/calibration number printed on the label from the donor truck
  • 590-7633 - Hollander interchange number

How to match your original: Check the white label on your original computer: SERV. NO. 12602802 (HDW NO. 12589162). Same Delphi case with two 80-pin connectors marked J1 BLUE and J2 GREEN, mounted under the battery.

Condition:
