If you plan on putting on fender flares and things like that you will need to get hobbyist plates, antique/collector plates require that the vehicle is fairly original in appearance.
Also I was wrong about the perminant registration, I had heard they were getting rid of it

Hoping for some help from the community.
All my mechanical is done. Driveshaft, booster, brakes, clutch, etc. I am stuck on the wiring. Here is my current setup.
1997 M62 OBDII engine harness
Tuned 88 pin 1997 540i ECU with EWS delete
1998 non-vanos motor
I am getting voltage to the dme since it is hard wired, but not sure if the DME power is hooked up. Anyone who has done another motor swap with any input?
Here is labeled C101, 2 relayed on the engine harness, white plug off the harness and DME (not plugged in).
I've got power and ground to everything (sloppy for now)
This is where I am confused. I know the black wire leads to my starter, but what about the rest?
I can get the starter to engage by hooking up 12v to it, I can get the fuel pump going. When I crank it with fuel pressure it doesn't fire up.
What am I missing?
For the record here is the C101 and DME pinout for this setup:
Any help would be greatly appreciated. I would love to get this thing running before winter hits.

Injector rails grounded? Getting fuel/spark?

garagistic has a little chart on m62 wiring: http://garagistic.com/index.php?page=e30-m60-wiring
i can't find any wiring diagrams online to identify that white 12-pin connector.

Thanks guys.
Not getting fuel/spark.
I need to make sure my motor is ground, doing that today after work.
Dan - I think you did just find it on that link - any idea what B/S mean? Wouldn't the socket and pin housing be the same?
That would make sense too because the only thing I was using for that white 12-pin was the starter out. I wasn't putting any V in to power the DME etc.
Edit - the table didn't show - it is the one at the bottom of the link you used.

Crank and cam are hooked up.
DME isn't bad?
I had an issue where my swap would randomly shut off while driving but the DME was still getting power. It would start back up but would do it randomly. Put in a new main relay and different DME and now it's perfect. I also re-went over my grounds. Harness, engine, injector rail and my e fan
Do you have a different DME you can try easily?
Fuel pump primes when key is turned?
-
so you got it?
my best guess for this was it was referring to which side of the connector and where it is headed. Basically male(pin)/female(socket) for that junction and everything 'socket' was on the side headed towards the body/other controllers and everything 'pin' was on the side headed to the DME. so your white connector is the 'pin' side, and the the 'socket' side is where its headed toward on the body.
B: Socket housing
S: Pin housingi wasnt positive, though, because your connector is missing some pins that are listed in the chart, although cars can differ from year to year
