e34 harness users pleas read

I am in the proces of doing my non-vaose swap and I have 2 questions
my e30 is a 1990 325i
first I am using this pin out to make my adapter ( thanks pierced e30)
C101 -- X20 -- Function
1 ---- 25 -- Alternator Charging
2 ---- 1 -- Oil Level (Static)
3
4 ---- 12 -- Coolant Temp Sensor (Gauge)
5 ---- 23 -- Oil Pressure Switch
6 ---- 22 -- 12V Feed for Diagnostic Plug
7 ---- 21 -- Ignition (Switched)
8 ---- 24 -- Fuel Economy
9 ---- 20 -- Engine Speed (Tach)
10 ---- 2 -- Oil Level (Static)
11 ---- 7 -- SI Reset
12 ---- 8 -- CEL
13 ---- 13 -- Fuel Pump Relay
14 ---- 14 -- Speed Signal
15 ---- 15 -- Starter (Unloader Relay)
16 ---- 19 -- Diagnostic Plug
17
18 ---- 18 -- Voltage During Startup
19
20 ---- 3 -- ABS Control

and last how did you mount you computer with the shorter harness? ( pics ftw!!!)
thanks

I made up a box to hold the DME in the extra battery space just behind the passenger strut tower. Picture was posted awhile back...

hey do you have the colors of the wires or am i asking to much because i am using euro 2.5 24v

i used a 50cal military ammo box.. looks badass..

I'm using an E34 harness and am having trouble getting it to start. My pinout is a bit different than yours is. I have the dynamic and static oil level pins switched, and I think I've got it right per the ETM. I'll know as soon as I fire it up though. Also, I used C101 pin 6 on the X20 pin 10 to make the E34 ECU think its in park as I pulled my harness from an automatic. Now, I have C101 pin 11 connected to the X20 pin 19 for a service interval reset and have C101 pin 16 connected to pin 17.

The first time I tried to start, I had C101 pin 20 wired to X20 pin 3 and it fried the connector. I put a new connector on and am not going to try the 20/3 combination without an inline fuse.

My current pinout (still not running...) is:
1 -- 25
*2 -- 2 Grounds when oil level is full
3
4 -- 12
5 -- 23 Grounds when pressure is low
*6 -- 10 Using O2 power to send park/neutral signal
7 -- 21 From ignition switch in start/run
8 -- 24 Tach/Fuel economy gauge
9 -- 20
10 -- 1 Grounds when oil level is low
*11 -- 19 Service indicator reset
12 -- 8 Has diode installed
13 -- 13 Powers fuel pump
14 -- 14 Speed output
15 -- 15 Powers unloader relays
*16 -- 17
17
18 -- 18 Powered in start position
19
*20 Unable to find reference

Is your car running with the pinout listed above in your initial email? BTW, I'm using a green label 405 with a D'Sylva EAT chip.

I have not had time to go back and recheck my harness ( car is still not running) I will hopeful have some time this weekend I will let you know

[88E30M50]

I've been telling myself that 'This weekend it will run' now for 3 weeks. My next step is to check the crank sensor gap again. I'm getting 568 ohms across the sensor, which sounds good from other threads. Still, the engine sounds like it would if it had a distributer and it was installed 180 out of time.

Thank Addisimo. This has been running my car for about 2 years with non-vanos e34 harness and 1991 e30.

[88E30M50]

I'll give this a shot today. Are there typo's in this though? I see pin X20 pin 18 is moved to E30 pin 17. All of the diagrams I see, and is evidenced on my car as well, show the C101 pin 17 empty. Right now, I have E30 pin 16 connected to X20 pin 17. I'll move that to pin 19 and give it a shot.

I also have the oil level sensor pins different, but don't think that would effect starting. I show E34 pins 1 and 2 to connect the oil level sensor and thought pin 1 was dynamic and 2 static.

My system consists of an early 91 NV M50 (build 10/90) with a green label 405 ECU (EAT Chip) and 88 325is chassis harness.

well I pulled the trany and slapped on a m50 flywheel and the checked the cam trimming and it is spot on, just got it all back together tonight and it sill back fires like a mother f'er but it will not start I am wondering if their is a difference between the front crank pick up wheel between a m50 and a m50tu. other than that I stuck I just can not finger it out anyone want to by it off me for 5k>? lol any help would be killer

[So Live]

I think the VR senors ARE different between nv and vanos motors. Are you using a vanos crank pos sensor? I think the cranks wheel is different too. I know the trigger angles are different.

[gregslow318i]

it runs!!! turns out m50nv do have a different front pick up wheels than the m50 vanso motors

[88E30M50]

Does anyone know the proper resistance for the cam position sensor? I did not find anything in Bentley's. The original reads something in the area of 1240 ohms across pins 1 and 2. The one I pulled from a junk yard yesterday ($5) reads about 1030 ohms. Is this supposed to be the same as the CPS, at 540 ohms?

I plan on checking the one in my E34 tomorrow to see what that one reads.

I believe it is close to 1200 but not sure
