I have acquired a 1995 grand prix se coupe and it needs an engine.
It so happens that I have a complete totaled 1996 cutlass supreme coupe that has the same options and 3100 motor. Could I pull the engine harness and computer from the cutlass and just plug it into the grand prix?
I know about the abs module and the trans switch needing to be changed. What will need to be done about the rear o2 sensor harness, does that harness run under the car or does it go through the body harness?

The cutlass also has a nicer gauge cluster should or could I swap that too?

I have read a how to here but it does not saw if the 1995 and 1996 is just as simple as just plugging in a harness and changing a couple things. will I need to modify the c100 connector at all?

I just found out that the cutlass has abs and the grand prix does not should I swap that over as well?

Thanks in advance!
