5/1994 M50 swap into 1989 325iC (wiring harness)

I'm finishing the wiring on my engine swap. Here it is if anyone would like a solid starting point:

the ETM's

engine: http://wedophones.com/Manuals/BMW/19...g%20Manual.pdf

here is the excel sheet I worked out from the above ETM's:

I don't have time to dig through the ETMs now, but if you pull the intake you should have no issue getting to the starter solenoid.

First off let me say you are lazy and you can paypal me for doing your work :-p. this should be everything you need for your car and the e36 should be searchable so I'm not doing that for you. These are from the link you posted that you said is your car.

5/1994 M50 swap into 1989 325iC (wiring questions)

How am I being lazy? I had already written the section numbers of the wires I'm asking about before you responded. How does what you wrote clarify the starting system? Is there a neutral safety switch for the manual transmission I need to connect correctly?

then I got tired of digging through the pages since I wasn't sure which ones to look at and the text wasn't searchable on my computer so I wired everything up like this:

I was joking around. You took the easy out using somebody else's diagram.

Have you tested for power at the starter yet? Simple things first. There is no neutral safety switch.

I won't be able to until Friday or Saturday morning

The loud click is probably the starter solenoid clacking. Could also be the gear hitting the flywheel. My guess is that you have it wired right but starter is shot or is only getting intermitent voltage. This is just an educated guess. My first check would be to jump the starter and check for 12v at starter solenoid.

is there anything I need to know about using the m50 starter wire instead of the m20 starter wire? I'm using the e36 starter but I read on the board that the m20 starter wire is less hassle...but the post didn't say why.

[justin_l_]

You can use either power wire. I have used both with no issue. If you pull the intake elbow you should have enough room to get to the starter solenoid. Might be easier to get at from under the car.

[mpowerful]

Shouldnt make any difference except maybe they meant the wire is longer/shorter and fits better? The only other wiring issue at the starter could be if you hooked up the unloader relay wire only to the starter solenoid post. That would give you no start for sure.

Alright, I'll check this all out tomorrow. Everything ran fine before I pulled the motor and I never disconnected the starter or starter wire...just bundled it all up on the engine stand so everything should be working same as before and doubtful the starter crapped out on me just sitting around.

[mpowerful]

Well what tranny are you using? Did you unbolt the tranny flywheel for any reason? Could be binding on the flywheel.

I'm using a zf320 trans. I did swap out the flywheel and swapped the getrag 250 out for the 320 trans I put in.

[e30rapidic]

I'm using the e36 starter

starter needs to match up with the flywheel

[mpowerful]

Check for 12v at starter relay with key to start position. At this point this is your best bet.
