I was going to ask you if YOU wanted some
Eko`s M50,On the road now!
Moderator: martauto
Hi Eko
Well I don't know if this might help as a start, but here goes.
The thick black wire to the batt terminal is the main power feed to the std E34 loom.
The thick red wire is main power feed to the starter motor (had to make that one myself).
The small red wire to the terminal is another live feed to the std E34 loom.
Ignore the red wire with the in-line fuse. Thats for the Clifford alarm system.
The funny little E34 block connector (left of centre), I've used as a joiner for the earth cables from the std loom. The red wire on the other side of it is because I was too lazy to change it to a black one. It's sheathed in black further along and goes to the Batt neg.
You can just see the relays sitting behind the wiring for now. I intend to extend those wires & situate them on the LH shock tower as per mormal E30.
I'm no electrical wizard, but if we start with the basics and work through it, we might be able to stumble across your problem & get you going.

BTW, I've had a damned good look & I still can't find anything that a lamda sensor could plug into
.
Looks like I'll have to ask Brian or Ian

Sooty,thanks for the pic 
My wiring is as follows,each ones position has been checked,double checked and checked again!
E30(PIN No and colour) E34 (Wire colour)
1,Blue - Blue
2,Blue/Violet - Blue/White

18,SW/GE? - Black/Yellow
Not sure which colours SW/GE represent
These are all the wires ive connected from the E34 harness to the E30 C101.
Engine cranks over fine,when ignition is switched on i can hear the White relay click but non of the others!
I have tried putting 12v direct to the Green/Violet wire and the pump is working fine,also tried 12v from the Green wire(coil +) but that makes no difference.
I have connected both Reds from the E34 harness(next to relays) direct to battery + and connected Brown/Orange and Brown direct to earth at strut top.
One thing ive noticed today is that the small spade terminal on the starter motor has nothing going to it,is this correct?
Really pulling my hair out(if i had any) with this now,obviously i dont know what the hell im doing when it comes to electrics.
Not even sure an auto electrician would look at it,due to it being 2 looms put together?

Ok Buddy.
I think you would be better going on pin function rather than colour. I know that the colours can change between various models/years & there doesn't appear to be a logical sequence to it.
I'll go & take off my link loom & we can go through it bit by bit.
I'll also check on my starter motor.
Back in a mo

OK - lets start.
First, I've checked my starter & I've got two small wires from the E34 loom running to the small spade (I'm using the M20 starter BTW).
With everything in place, it's nigh on impossible to get a pic but I'll try & get you one tomorrow night. That OK?
Here's a pic of the link loom that I made up to join the E34 X20 & E30 C101 plugs.
Have you got a small multimeter to check for continuity between the pins?

Sooty-Im using stock M50 starter!
Was going to make a mini loom to connect the 2 but on Ians advice opted to just splice the M50 harness into the C101.
Ian sent me a PM this morning,saying the fuel pump etc isnt going because the ECU isnt telling it/them too.
Give me your email and ill send you the original email and attatchments of wiring diagrams Ian sent to me,compare it direct to yours?

Whichever starter you have, there should still be some wires going to the spade terminal.
That's what gives the power to pull the solenoid in & engage the starter with the flywheel.
Is the engine cranking over or is it just total zilch?

eko
i know this is off topic.
but you dont want to use that diff. it will do about 90mph top end. no word of lie.
WTF? Then where's your solenoid drawing it's switched ign power from?
What am I missing here?

Sooty email on its way!
Sw (Schwartz or Black) / Ge (Gelb or Yellow).Not sure which colours SW/GE represent
Ian's a pretty switched on kiddie when it comes to this shit & he's probably forgotten more than I will ever know, but I'm a bit confused about pin 16 (Wh/Bk).
His listing suggests that the E30 has an airbag??????
That's a new one on me.
Let me go through that little lot & I'll get back to you

Just sent an email with the PDF files but it's taking a long time to go so it must be a bigger file than I thought.
Delete it if you can & I'll send it through in two goes to try & speed it up a bit.

There should be a large diam cable from the battery to the large terminal on the starter. This is the main power feed to it.
The same terminal should also have a slightly smaller diam wire that goes to B+ on the alternator. That's how I've got mine set up.
Sometimes, the battery cable goes to B+ on the alternator first, then links to the starter but whichever way round you have it, both the alternator & starter have got to be linked.
There should also be a smaller Bk/Y wire to one of the small terminals (numbered 50?) on the starter. This is your switched ign feed to energise the starter solenoid when you turn the key. According to the wiring diag, this should go through pin 18 of the X20 plug.
In addition, there should be another Bk/Gn wire (smaller again) that goes to terminal 30H of the starter. This goes via pin 15 of X20 and feeds the SRS module, the on-board computer & a general module in the E34.
We'll start from this and work through it.
Just going to try & send the PDF's again (one at a time this time round)

but all the above go thu the X20 plug right?
I mean,the engine/wiring are as they came out the E34,only things eletrical disconnected were the AFM,starter and i think that was it?
Main X20 plug was unplugged and ECU removed.
So with this in mind,surely the starter/alternator wiring will only be wrong at the C101?
Looking at the list you sent me, the relevant wires are there at the X20.
The C101 should'nt come into it
When you disconnected the starter, can you recall taking anything off the small terminals?
Could the wires have been tucked away behind something?

Trouble is,i didnt unbolt the starter,Benjy did and hes away at sea for a month so cant ask himSooty wrote:Looking at the list you sent me, the relevant wires are there at the X20.

I did have a poke around the starter today when i noticed the empty spade end but couldnt find any loose wire?
Would that stop the fuel pump/spark tho?
I've got am M50 starter tucked away in the shed & I'm certain it has the large M8 terminal for the batt cable and two small M6 terminals on the solenoid so I don't think you could have got them mixed up.
I'll definately get a pic of mine when I get home from work tomorrow.
Any chance you could have a look for any loose wires around your starter and get a pic of yours?

It should'nt, but it's puzzling how you can get the engine to crank over without the solenoid connected.Would that stop the fuel pump/spark tho?
It's looking more & more like you have a couple of wiring problems rather than just the one & there's a chance they could be inter-related.
Don't give up hope just yet m8
We'll get to the bottom of it.
Will do tomorrow!Sooty wrote:I've got am M50 starter tucked away in the shed & I'm certain it has the large M8 terminal for the batt cable and two small M6 terminals on the solenoid so I don't think you could have got them mixed up.

This really hits home how little i really know about electrics?

Don't worry about the spare connection on the starter. It's empty because of the way BMW wired the early cars.
On early cars, they used the same starter connection for both the solenoid drive signal and the unloader relay connection. On later cars they used a separate connection for the unloader relays. Your spare connection is used on later cars, but not early ones.
Have you checked to see if the fuel pump relay is pulling in when the engine is cranking yet ?
Confirm you have 12v on both the red/white wires, and then check the brown/green wire goes to ground when the engine is cranking. If this wire does not get pulled to ground (by the ECU), then it probably can't see the engine is cranking. If it can't see this then it won't do anything.

Just found this! What an excellant thread - But what is it doing in the PHOTO GALLERY!!!!!!!!!!!!!!!!
This is the reason your not getting the help you need. No one's seeing the thread!
I notice I'm the first mod to post here. Ian's apparently been answering questions via PM - He must be wondering where the thread is.
Don't want to mess up this tread or lock it, but its got to be relocated to somewhere more appropriate!

I wondered why I hadn't seen this before. Had not spotted that it was in the Photo Gallery as I followed a link that was sent to me. This needs to go to the Engine conversion section really. I'll move it and leave a shadow so that everyone can still find it.
