Hey r3v, I just bought almost everything to do a M50 swap into my 1985 (84 build date) 325e and was wondering what i have to do to wire in my new engine. I cant seem to find a C101 connector and ive read that the really early cars don't have one, is this true and how can I make this work?

They still have it, it's just square and on the other side of the fusebox

Thanks! I just found it. I also read that extra wires have to be ran. What are they for?

I ran extra wires for:
-Tach
I traced the C104 wires back to the cluster and tapped into the tach wire (black) there, ran a wire to appropriate pin of the E36 harness
-Econoguage
Same as the tach but it's the yellow/white wire
-CEL
The DME uses a switched ground to illuminate the CEL. I mounted a little LED in the dash, provided it switched 12V power (from the stereo) to one pole, and ran a ground wire from the correct pin on the E36 harness to the other pole.
-VSS
I had to solder a wire to one of the three pins on the green connector on the back of the cluster and then ran that to the correct pin on the E36 harness.
-Oil Level Sensor
The oil level sensor has three wires: Static and dynamic levels and a ground. I grounded the brown wire to the E36 harness and ran two wires through the E36 harness, through the connector, to the correct E30 pins.Comment
