[MOODY]

Hi there all I am converting my j reg coupe a m40 318i to a m20 325i I need to know is it a straight plug and play or will I need to alter a few wires I.e the c101 plug

If the M20 is from a facelift car it should be plug and play.
The only thing you must check is Pin20 of the C101 - If you find a brown wire on the body side of the C101 it needs to be removed, otherwise you will be connecting the live ABS feed from the M20 loom to earth.
