E420 loosen ecm wire
I would need some kind of wiring diagram for that ecm wiring connector, because i have no idea where this wire is from. And im not even sure was it on loose already or did i accidentially pulled it off when i took ecm off.
Wire is red with green stripe.

Thanks already, and sorry for my bad english.. mine native language is finnish.
I'm able to look for those wires only in next weekend, because I'm not home right now.
But last time I did check that big connector and I didn't noticed any pins without wire.. On the other hand, I'm not 100% sure. It surely would be alot easier knowing the right pinout.
No. 48 = white
No. 49 = black
No. 53 = brown/white
No. 40 = 2 green wires
So, should i put that rd/gr to no. 44 or what? There is no connector for that wire..
Maybe there is a reason why its loose? I dunno...
FYI, the wire has to have a connector(pin or blade) for the data to flow to the ECU---are there any positions that have a connector but no wire???
My car wont start.. it cranks but just wont start. Somekind of immobiliser problem.
But i have ordered new key and probably will work after that - i hope.
If i recall, error code was p1570. Something of ifz.

Bronze is really good, but gold would have been alot better.. heh.
Actually my car hasn't been running since last october. I had my engine off and worked with some rust. So there might be just some wire loose or something.. i dunno.
But before that it worked like a charm.

And now even the remote lock wont work if I push button from key fob.. there is no red or green light.
Damn, this thing is driving me crazy.

I have attached those fault codes what carsoft gave.. hope it will give at least somekind of clue.
And now the situation is that i have finally managed to get engine to it's rightfull place but it wont start.. it cranks but will not fire.
Car's history is mystery to me.
New key is real deal from dealer, straight from German. And i only bought it because I only had one key.
I wouldn't count for all those fault codes, it's not star diagnosis.. just a crappu carsoft.
