Standard motor products # EMO 481 or EMO 481u these are Reman ECU units $191 and I see AC Delco has them reman also # 218-12292 $ 388 but have the auto parts store double check those numbers because there usually is no returns on electrical.
My mechanic told me to make sure to get one that will match the motor ie: thru VIN#
