Wire adapter help.

I'll have my adapter out and on the bench in the next day or so and should be able to help you verify a few things.

Now anything i say here may not be CORRECT information, just going by my charts.

15 - 15 looks right.
6 - 22 not used
16 - 19 not used.

So, Ive spent damn near all night looking at wire schematics and posts and everything for the adapter for my swap. I have a c101 and x20 connector for making the adapter, a bit of extra wire and my crimpers. Im going to post up my diagram for the adapter, if anyone has any input on it, please let me know. Car is a 89 325i and the harness is a 94/95 e36 harness. Question marks indicate what im fairly unsure about.
