Convert my S500 to S55 AMG compressor?
I'm fairly new here and bought me a S500 Long from 2000. I have received an offer and buy an E55 AMG engine from 2003 pretty cheap. so I wonder what's needed to be done to get it work.
Had a CLK 430 before I stop in a W210 E55 engine it went very easily and also has been watching to do so in my S class but would have been nice to have a compressor.
*I have checked a little self. and talked to one who can program if the box but what I found so have they changed Box 2003 annnan against I've had them done on the W220 and W211 have the newer box. so the harness from the E55 engine will not fit in my box. can solve this without costing much.
differ much in my original harness the E55 engine?
or is it difficult to change box? I need to replace nykel and everything like that too few new box work? found some S500 boxes in Sweden from 2003 would fit then later add the right software in it.
What are your views and suggestions? grateful for all the answers
