Hey yall, I just logged into this age old account for the first time in forever and long story short, used to own stock manual e34 525i's in the past, well, I missed it and found a 95' alpine white 95' in immaculate condition but it was auto with the gm france auto. Bought it, found a getrag swap and tossed it all in, pllanning to stay mostly stock thats why, got up to the wiring after installing the trans with EWS2 and I am not firing up. It cranks, no trans program error after following the thread for 95 e34's wiring and it wont actually fire up. I grounded the brown wire from the blue plug, removed the gray wire, and looped the EWS2 yellow plug, the car cranks but wont fire up, I am not good with electrical and my understanding is very basic, the car shows "E" on the shift display for a few seconds then disappears, is that all to the wiring or do I need to do something else to tell it its not an auto anymore and tell it it's in park or neutral? 95 e34 manual swaps are few and far between and I am trying to follow them to a T so I can get it running, maybe it's my lack of electrical knowledge idk. Any help is appreciated!

pretty sure I just resolved this, I followed the bmwe34.com website wiring to a T up til the 95+ part, my car is a 05/95 build so has EWS2, EWS2 has no relay plug in the engine bay or the kick plate that most refer to, the relay is a big yellow plug under the drivers dash on the left side. Slide the yellow connector to the left and pull it out. All the write ups say to "Bridge" the black yellow wires together and leave the connector unconnected but this is why my car isn't starting is because the plug is not connected. The write ups say to do this but for me it does not work, I found this super useful thread for 95 e34's manual swap wiring 1995 525i 5 speed swap EWS2 problem (bimmerforums.com) (https://www.bimmerforums.com/forum/showthread.php?2345267-1995-525i-5-speed-swap-EWS2-problem&highlight=speed+swap+ews2+problem)
credit to @greatkazou and @killian665 for this great wiring write up, instead of bridging terminal 2 and 6 on the ews module, just remove the two black/yellow wires from 2 and 6 and join them together and then plug the connector back in. Voila.
Hope this helps somebody in the future as bmwe34.com lost half of it's images and these older threads using photobucket have the pictures expiring, it's starting to get hard trying to wire stuff that you can't even see what they look like from the get go for a noob like me.
