So you have a E34 with a 2.5 that you are swapping to a M50 2.5.

Is the M20 connector square or round.

From there you can decide the adapter.

You are going to have a distribution block no matter what. If you can easily move the battery its nice to have it out of the engine bay.....

the m20 connector is round....so you mean i would have to rip up the interior to move the batt to the rear?and what kind of adapter will i need and were can i get it?

You might want to look at getting the Orca CD.

No, you dont have to rip anything out.

You need to
A) Find / Make an adapter for your motor to chassis. I would make it if you have some electrical skills. If not, try buying one from a member who is making them.
B)Figure out the battery situation. You should be able to just run some wires off of it, A lot of the hookups are going to be to the fuseable link and the B+
