m20 into a 318i
I have all the mechanical hooked up and 95% of the wiring. I need to know if anyone has put a m20 into a 318? I need the colour codes from the 318i harness and the colour codes from the 325i connector.I figure I will run this engine for a bit while I look for a good m50.Thing is it needs to run first..:D

But you are pretty far away man. We would have to do it by phone or scan a few key pages.

Thanks for the help. Anyone else want to lend a hand I would appreciate it. This will give some valuble insight on how to upgrade to a m50 later on.

here is what was posted on another site
Ok This is From The Engine side of the plug on the 318i to the Chassis side of the plug on a 325i Engine.
Violet/green-Violet/red(both large guage)
Green/yellow-Green/yellow(both large guage)
Greeb-Green(both large guage)
Black/yellow-Black/yellow and (smallguage) black/green
Left on the 325i side You'll have a Yellow/White wire(Fuel rate ouput)
Black(Engine speed output)
Brown/black(Check Engine light)
Plus some other wires but I never found there functions.
I never tested this plug and made the conections based on the Feature that wire did and not it's color.
