Has anyone used the B30 manual harness before? I have one and noticed that the 3.0 harness doesn't have the x20 connector on the passenger side of the harness just the diagnostic connector. Is there another way they wire it up to the e30 or should I use my 4.4 auto harness???

Has anyone used the b30 manual harness??

[JGood]

Yes, there's a sticky at the top of this forum dedicated to that exact info. The b30 harness does have an x20 connecter, just as the b40 harness does, same location.

As a sidenote, B30 harness has different knock sensor connectors.

As a sidenote, B30 harness has different knock sensor connectors.

That's a date specific change, not a b30/b40 change. I forget the exact date, but all b30/b40 engines before a certain date use the old style knock sensors.

I will get a pic of the harness, but yeah it has the same style knocks as the 4.0

Installed injectors today


Coming together soon! Ordered more things, trying to get the most power out of this this I can.

An this is my b30 harness

can you take closer pics of the relay side of the harness for me with all the exposed wires? I'm trying to figure out what I'm missing on my O2 heater relay.

[driftingminor913]

Ok I will try, n also I think I found my X20 harness connector....but it's not a circle like the rest it's a square one? Anyways I thinks it's a tad bit easier since it doesn't have to many wires running thorough it.

[driftingminor913]

Does anyone know what this connector is called?? I'm having trouble figuring out what this is. I was told it was pulled out of a Manual 94 530i E34 but I know that the 94 e34's had a x20 (circle plug) and this harness doesn't have that as you can see its a rectangular plug...




And like I said there is no circle plug on the harness other then the diagnostic plug

That's not an m60 harness, that's an m62 harness.

driftingminor913 - That's not it, it should be on the plastic housing itself on the e32/e34 harness like this below (it's most likely going to be 25 pin, not 20 pin btw)

[driftingminor913]

That's not an m60 harness, that's an m62 harness.

What's the difference from the m60 & m62 harness?

[Vtec?lol]

The m62 harness goes straight to the electronics box and has no connector for anolog chassis control (x20) which is what you have. That harness is for can-bus systems.

That's not compatible at all with the swap. Whoever gave it to you lied.

Lots.... get another harness.
