I think Wes can tell you from the VIN.

That should not matter... I have a 90Cal with a 93Fed ECU... no problems there. The only difference between the two cars is the EGR temp. sensor (which is ignored by the federal ECU), and a different catalyst part number... otherwise the cars are identical. I might be concerned if you put a California ECU in a Federal car (it would be looking for the EGR temp. sensor circuit that's not there) but not vice versa.

Dont forget about the extra temp sensor under the plenum (in the Y).... Either way, theyre cross compatible.....Q451990 wrote:That should not matter...
