E30 Gear box , 4hp22 . Please help

[jamdogg__cat@hotmail.com 0]

Hey guys!!

Right so I have a question, I have a 1988 e30, 318i.

It's got a blown trans, so I've got a new gear box that's been recondition , with recipts.

Before I bought I made sure it would fit.

Now I've come to fit it and the gear box I removed from my car has a two pin plug

On the passengers side of the gear box behind the selector.

And the other one doesn't , I know it's not the kick down cable , or speedo as that's in the diff.

What else could this be and will my new gear box fit without this cable being plugged in?

Any help would be much appreciated ,

Thanks
