Can anyone tell me where the PCM is located at on a 90? Is the PCM the same as the computer?

Thanks,

I bought a Chiltons manual today for this model. According to it, a 90 model does not have a PCM. It uses an ECM if I read this correctly. Can someone verify this? So, I guess now the question is, is the ECM and the computer one in the same?

Thanks,

ECM=Engine Control Module
PCM=Powertrain Control Module

The difference is the PCM also controls the trans where the ECM does not. Technically, your 90 has an ECM and it's located above the passenger's hush panel. Kinda behind and below the glove box.
