[e92mirro]

engine is in now in and sorting the pluming this week.
With the end now in sight the last bit of info i am going to need is the wiring diagram. Is there a link or somthing for this info or a thread on the zone.
Cheers guys any help given will be apreciated

Hi mate! I followed this wiring when I fired up my engine this weekend. Start off with this, and if you get any problems just ask me again. There may be some changes.

Tried it out? Does it run?

[e92mirro]

still on the exharst manifold at the mo! Trying to mod the standard pipe's from the s50 but is starting to develope into a head ache!

[Larsen-Racing]

You rund RHD car I assume?

Here's mine, modded with parts I cut off;

[e92mirro]

Is that manafold mod for a lhd car? My Right hand bank seems to be in the wrong place aswell!
This is the last few bits left to do now so getting realy excited

[Larsen-Racing]

That is for my lhd car yes. You can also heat and bend the manifold, I know some people do that.

A bonus I got when I welded the manifold like I did is that I can take them out while the engine is in the car.

[e92mirro]

mine has ended up a bit more spageti junction as i have the steering uj to contend with and i have managed to keep the length of the pipes the same
I havent tried to remove the manifolds yet but the uj will have to come out to even try and remove them

[Larsen-Racing]

I had to remove the front manifold to tighten up the top nut on the engine rubber after mounting the engine in the car...

Shocking

Good job on the manifold BTW

Depends on what motor mounts you are running and how the engine is placed.

I have a lot of tools, but it was impossible to get any socket or spanner onto the nut.

Hi everyone,

I am currently doing a s50b32 swap into a 88 e30 m3 and I just want to know if the wiring diagram above is correct. Also what wires connect to the power distribution block. Thanks in advance.

didn't you say you have this sorted from Rui????

[sonnyqm3]

I am using the diagram from the forums and what i saw from Rui's work but my old car had a MZ3 harness. I just want to make sure that everything is in the right place.

Hello,

I realise I might be late to the party, but I was wondering if you can help with something.
I'm doing a conversion E30 325i convertible 1990 (shell) and S50B32 1996 E36 M3 engine.
I've purchased a loom connector and realised that the guy had done it wrong.
I had a look on your schematic and I see that pin number 8 on E30 is missing, but I have it on my one and some other diagrams are telling me to go to pin 24 (E36) which in your case is blocked by pin 16, but I don't have pin 16 in my E30 connector.

I also have 2 more pins which are not occupied by your legend: 18 and 20 in the E30 connector.

Any advice would be much appreciated!

Cheers!

Just to comment on the exhaust manifold issue. I managed to source a second manifold and used one of the pipes to replace No6 which was hitting the bulkhead and steering. Now all the pipes tilt towards the front. Obviously some welding needed. I used a sleeve on the pipes so as to be able to follow the same path as the other pips to the collector. With the manifold off I mounted/bolted it to a piece of metal before cutting off No6. Still got that piece 16 years later. This ensured that the new No 6 was perfectly lined up after welding. If this is of help, great, if not then ignore
