Engine block should be the same? Both have electronic climate control (not excactly same by the looks of it) But the compressor pump should fit right?

it should with no problem. Both compressor's should be made by Nippen Denso and are interchangable. I just did this on a friends car. We put a used compressor from a 86 5000 onto his 1990 200 TQA.
