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

Yes! Was it the pin connector thing ?

Yes:
The two green wires needed 12v. One to activate the fuel pump relay, red/white wire, (which I was using a go around for) and the other to turn the ECU on.
Black is starter which is hooked up to the C101.
Ordered a huge Z3M 3 row mishi last night to keep it cool. Hoping to get it on the road Sunday and have the bugs worked out for the fall meet.

I know those feels. I hope to see the car this weekend!

Nice work man! One step closer is always a good feeling

Alternator is pumping out energy now, not leaking a drop of anything, motor running smooth, and making progress on some of the data going to the cluster.
Bad news, mainly is the brakes sink to the floor and don't come back up. Im thinking it could be A. air in the lines. B a bad master cylinder (no leaking though) or C the spring to return the E30 brake isn't strong enough for the new setup.
Other than that small stuff and busy work getting the car put back together.
