M30b35 swap into 1990 vert *NOW WITH LIFE!!*

[Mr. Burns]

thanks all, even spoke to Frank M. regarding the choice, and b35 harness hands down.

Thanks again for the continued support R3V can't wait to get back in the garage and keep going:D

The b35 injector cover really ties together the room... err bay :)

In my swap, I used the '92 m20b25 harness. I had to clip off the plastic injector wire cover, but all the wires were long enough, except for the charcoal can wire, I think.

It would definitely look cleaner if I had time to put the b35 injector cover on it.

[Mr. Burns]

You're right...
Jeeesh long day.
Throwing in towel

[CorvallisBMW]

One is probably for the trans computer, if it was an automatic b35 car

[Mr. Burns]

Not so much fitment but the cleanliness of the final fit.

Also I seem to have two long rectangular ECU ports on my b35 harness??
1 cruise control?

When I finish my swap this will be a 100 page thread:( sorry R3v I'll donate more $ lol

Corvallis my e30 is a 1990 m20b25 (manufacture date Oct 1989)
I uncliped each individual lead from each injector.

That one euro, my b35 harness is uncut and working completely fine.
I've read about fitment issues with it however...
I would much rather stick with the b35 harness TBh it seems a bit more logical.

What fitment? I mean yea it's tight but completely doable. Save yourself time and stick with the b35 harness. It's plug and play with your car aswell.

Yea if just stick with the b35 harness if it's uncut and working. I'm running the b35 harness

[CorvallisBMW]

Yes, you'll have to unclip and remove the whole m30 harness. What year is your m20 harness? Unless it has the individual leads for each injector, you'll have to do a bit of work to make things fit.

[Mr. Burns]

Scratch that. From what I'm reading the m20 harness is just as good and a cleaner install.
As long as it reads 1.3 motonic I'm good.

Question:
My M20 harness just clipped off more of less. The b35 harness seems hardwired into the injectors. Am I missing something to undo or unclip to remove the full b35 harness?
Thx for you help fellas

[Mr. Burns]

I have a full uncut m30 b35 harness still attached to my M30b35...I think the most logical approach would be to use that harness no?

[Mr. Burns]

Update.
Self explanatory.
Engine/tranny/driveshaft and exhaust OUT!

I regretfully removed the entire wire harness throughout the process with the starter attached.

I'm going to try and re-install the wire harness back into the engine bay to the best of my ability.

I did not label anything tho...perhaps I'll just wait until I drop the new engine in and go from there...
Either way, tadaaaaa

[Mr. Burns]

update.

stuck at driveshaft vibration dampner.

I hate being under the car. Need to reposition and re-re car in air in order to hack away at the biatch.
will need to drop entire exhaust, heat shields in order to access center support bearing and lower at half shaft to be able to access bolts at guibo in order to separate DS from tranny.

a 5 minute job is turning into potentially a couple hours due to this stupid vibration dampner business.

QFT

Mine are getting a little older and more independent now at 5 and 7. Praise the Jebus.

count yourself lucky you have two!
my stepson is a single child, but requires non-stop attention, and I feel bad when it's just my wife that has to entertain 24/7...
@7 years old it's still tough.

oddly, these little jobs took longer than I had anticipated...
I can work in about 1 hour slots lol

tonight i'm going to remove the 2 tranny mount bolts and start the diff

Thursday exhaust manifolds.

Saturday/Sunday deal with A/C (still charged) and pull the whole lot...

I'm a little miffed at the mess I'm creating but it is what it is.
