It does not fit since the connectors are not similar.

My 1994 Oldsmobile cutlass ciera ECM fuse keep blowing, the computer at O'Reilly said that it is the auxiliary wiring, What does that means???

i would expect it mean's the wiring harness to the ECU , most likely has a break somewhere and is earthing out , you will need a auto electrician to trace the fault , electrical problems are a nightmare , look on a Oldsmobile internet forum some one may know where to start, or recommend a repairer

Im lookin for the computer in a 1994 chevy blaser s10 anyone know where its located?

The computer or powertrain control module (pcm) on the 94 s-10 blazer should be located under the passenger side glovebox you remove the lower glove box screws (under the dash) then remove the pcm retaining nuts to lower it out of the dash I have found this easier if you take the passenger side seat out to give you more room to manuver on some of these it may also be located on the passenger side fender under the hood & near the shock tower it is large with a few big wire harnesses goin to it each harness is color coded to fit where it goes into the pcm

Trying to wire a 1994 lt1 into 1996 chevy s-10

It should be a plug and play if your using the ECM for the 1994 engine. The ECM on the 1996 S10 will no work on the LT1 engine, for one thing the S10 ECM will only command for 6 fuel injectors and will have different injection pulse and so on. The program of the S10 ECM is made for the Vortec as to the LT1 will have different parameter **** as engine running temperature, vacuum readings, and timing.
The most obvious would be the 1994 LT1 runs on a OBDI system and the 1996 is running on a OBDII system. You can still run the 1994 LT1 from a 1994 with a OBDii system ecm, but some of the sensors will need to be upgraded to accommodate for the proper readings the OBDII system will need to have the engine to run right.
If you don't have the right ECM for the LT1, go to the wrecker's and locate one, Caprice, Camero, Firebird ECT.....
Thank you for using fixya and good luck on your project.

Will a 2001 4.3 fit a 95 4.3 I have a 2001 Rolled s10 blazer w a 4.3 and an automatic trans will this fit and work in a 1995 s10 blazer that had a 4.3 and an automatic transmission

Yes it will but your going to have to also transplant the ECM. The change off years to the Blazers are 1992 to 1995 and interchangeable, 1995 being the odd ball year for the 4.3, and in 1996 to 2002 are all drive-train interchangeable. Good luck and keep me posted if you have any more questions.
