e36 e46

Hi all I’m looking at getting an m52 engine that is out of an e46 to put into my e36. I know the wiring is slightly different but does anyone know what wires need to be sorted on the loom so I don’t have to spend another £250 on a loom. and help would be much appreciated Thanks

Currently running cut hubs, standard rack, standard arms and cut inner and outer rods. Looking at fitting e46 arms, will the cut inner/outer e36 rods need replaced? Currently cut 10mm outer and 20 mm inners I'm sure.
