Any info on M51 swap

[E30 tds]

Any information on the M51 swap would be helpful.
currently finding it hard to wire all the cables needed for the swap.
and the oil pan is hitting the steering rack with the engine on E36 tds mounts and M21 rubbers.

There haven't been too many M51 swaps on here, but there's a pretty comprehensive site here:

The donor for the swap was an e34, but a lot of the info should be relevant to your swap. The wiring pinout is on the site.
