M30 swap

How does ur shifter sit inside the car my slector rod was too long

The shifter is a from a short shift but it sits a little lower than stock. Funny thing is when I first started the car after the swap and put it in reverse the guibo kept hitting the selector and popping it out of the shifter. So after several times of doing this and me putting it back into place I got under the car. I had put the selector rod upside down . I flip it and now it works perfect.

M30 swap

What length did you make selector rod and shifter arm

Sorry I just saw your post. I didn't have to do anything to the selector rod. It fitted just perfect.

Yes. I was just looking at the ETM for the 735i and the injectors are wired in threes. 1,2 and 3 fire from ECU port 14. 4,5 and 6 from 15. So since the M30 firing order is = 1 5 3 6 2 4, with 1 being the closest to the radiator then it should be easy to figure out the plugging order.

Injectors are fired in two batches of 3s. The easiest harness is the one that came on the engine, the e32/e34 harness, will stand by this statement to my grave :)

True that!

'87 and early '88 is the easiest harness to use for sure.

Later ones too, but you have to tear apart that damn plastic housing. doesn't look as pretty, unless you can get a B35 injector cover.

it shouldn't be hard to identify them even with the numbers gone. the #1 and #6 are the longest and the 3 injector connections with the blue and brown temp sensors are obv for cylinders 1,2,3. Im using an m20 harness

I have never done a swap before so the learning curve was steep

depends how competent you are but for newbies this is easiest

Yes, some of the plugs have a yellow tag with a number. Is that the cylinder number?

Yessir. I'd match those up, then the other fall into place, deductive reasoning. All of the wires should have the # on it, but they get lost over 20+ years.

After '87 the injectors got put into a plastic housing. In '87 they have the correct ECU plug, and the injector wires are open. Before '87 the ECU plug ans't correct to fit a 179.

I'd lay the harness out and the injectors plugs pretty much fall into place. Some may even still have the #'s on them. They will pretty much only reach where they're suppose to go.

Its just the injectors plugs are kind of out order and just need to verify that.
