Recently did this the non intrusive way, not a single wire spliced. Info is in the thread above.
Really easy.
I removed and refitted the front springs on my Z4M with some real basic spring compressors. It can be done and it wasn't as sketchy as I was expecting.
You just need to get the position of tje compressors right so you are compressing as much of the spring as possible.
No, there is no wire to splice into on that side of the connector. You either need to install the wire from the cabin into the pin 4 of the black connector using the pin I mentioned.
Or splice into the blue wire running out of pin 4 on the female side of the black connector, that goes into the...
I did mine on my ///M when I was replacing the diff input seal.
I suggest marking a line for the CSB on the chassis before removing. This removes any questions over if the bearing should be pre loaded 5mm or not.
Febi do reboxed OEM parts for the CSB and guibo. Both of mine were removed...
I realise that the market for the ///M's is not huge, but as time goes on both genuine and aftermarket parts are seemingly harder and harder to get and more and more expensive.
I'm usually pretty creative in finding parts or solutions, and have certainly found a few so far for my Z4M.
Examples...
I've just done mine, I did it slightly differently to others - I didn't splice into the LCM, I took the power feed back to the fuse box as per factory. But it is literally 3 wires to install. Power ground and one to the ECU box.
Where are you based. And do you have the parts?
