My name is Jeff. I purchased my first BMW about 2 years ago. It is a 1996 BMW 328i Convert. It has high mileage (~180K), but I love it! I have had a new top put on, replaced the ripped seats and replaced the radio.
I am just about complete on a cyl head replacement, but am having some issues with the harness. This is why I found and joined your site. Wanna get her running and get back to fun times.
Rode her too hard and overheated her, next thing ya kno her water broke, steamin out her back side.
So now I'm puttin her back together and am having trouble with where to plug in all the connections (inadequate marking). There are 2 female connectors at the end of the fuel rail, 2 (1 male, 1 female) in a sleeved cable run and 1 female in a sleeve. So I need to ascertain which one goes to the VANOS, EGR solenoid and bottom of the intake connection. Trying to figure it out from the Bentley Service Manual Wiring Diagrams.

At the end of the rail there should be three (only two on my M52), one for the Vanos solenoid, one that connects the Cam sensor under the middle of the inlet manifold (long cable) and another that maybe you can see if you look between pots one and two at the same manifold... HTH
Eso es todo! Please press the "REP" button if you are happy with your response/answer...
You are soooo right! It became glaringly obvious once I re-installed the intake. The connector at the end of the fuel rail harness (rigidly mounted) was the logical choice for the VANOS and the one betwixt the intake horns (cyl 1 & 2) went to the EGR Solenoid. The one for the Cam sensor I had not disconnected, as I had to remove it from the head anyway. Thank you Dabsy for your Bavarian Motorwerkz Wisdom (BMW) Nice!!!!
OMG! I thought I was ready to turn the key tonight . . . Everything looked together, oil was full up, now to just fill the cooling system . . . and what do I hear? Water cascading down under the car from beneath the intake! Damn it Jim! I forgot to put the hose that goes forward to the expansion tank back on the distribution pipe from the timing chain cover!! Well, tomorrow's another day. Hope I can get my hand in there!
Well, I lit her off last evening and . . . IT'S ALIVE!! Not without event tho. So there she was springing to life and me scurrying about to make sure all was well with her, then I peer beneath her and . . . Whiskey Tango Foxtrot!! A pool of crude was forming!! Arrrrrgg! Of course I neglected to tighten the lower chain tensioner! However subsequent to tightening that the hemorraging stopped. Now I just need to find out if the louder than previous tappet or injector noise is an okay sitch. Now it's time for a road test! Wish me luck!
She's amazing!! I checked her vitals, idled her for ~30min and the tappet noise subsided! Quite pleasing! So then it was a bath (4 both of us), off to the parts store to return the unecessary MAF sensor (~$300 back in me pocket) and off to do freeway trials . . . In a word . . . ELATION!!
Top down, big pimpin (LOL) yet again! All it took was ~month ~$950, but the experience . . .

Well I've logged ~300 miles on the head replacement and all seems to be good. I have smelt an oil on the exhaust odor now and again, but haven't found any evidence of leakage nor noted any loss of oil via the dipstick. So it could be some one elses vehicle, but a watchful eye will be required. I'll probably gain cofidence over time, but am relectant to push her too hard yet.
