Bumping this.
Hopefully the OP has a good setup by now.
What isn't mentioned in this thread is the need for coding the ECU to tell the suspension that there's a trailer back there and it turns on the BMW anti-sway. Depending on the BMW model year, it also codes the trailer brake.
Here's the technical on the e70.
