Land Rover Repair/RR Full size EAS compressor into LR3


Firstly, sir it is indeed an honor to email you directly.  I have read many or your articles. I am on a one man rescue mission to address broken Land Rovers, way out in Canada.

My question revolves around the actual differences in the wiring of the RR full size air suspension compressor and it's field compatibility with the LR3.  What wiring changes are needed other than the obvious?  There are two white and two grey small gauge wires which can only be identified through plug routing which is different between the two models.  So once the mechanical install is complete, there remains the re-wiring.  

Your time and help are greatly appreciated!
Thank you in advance!!

I have never tried to adapt the RR compressor to fit an LR3.  Here in Massachusetts, both compressors are readily available.  If there was a prolonged backorder for one or the other I might try it, but that's not the case today.  If you do try it, let me know how it works for future reference.  Sorry I can't be of help otherwise
