I made a plug and play adaptor for (non ASC) ABS unit from 1996 328i to plug into my late model 1998-1999 E36 ABS/ASC-T 55 pin connector.

ASC-T system will apply rear brakes if the rear wheels are spinning, that is something you don't want if you plan on racing. I am not but I had to do it because I did a S54 swap.

Wiring:

55 pin abs/asc connector 1998-1999 models to 41 pin connector 1996 ABS
-----------------------------
55pin - 41pin

1-17
2-na
3-26
4-9 (I used ign cut off signal green/white wire from DME then wired it to "abs pump on" signal on the ABS relay, so that I don't have to run wire directly)
5-na
6-na
7-28
8-na
9-na
10-14
11-36
12-na
12-1
14-na
15-32
16-na
17-24
18-39
19-41
20-na
21-na
22-22
23 all the way down to 28 will have no connection
29-13
30-16
31-na
32-29
33-na
34-42
35-19 and 8
36-27
37-40
38-na
39-24
40-2
41-na
42 to 44 no connection
45-35

47-15
48-37
49 to 51 no connection
52-23
53-na
54-25
55-39

thats it, and it works, keep the existing relays. The ASC-T switching valves have two more ports for the rear wheels, I wired them in the series as you can see on the wiring pinout, please use wiring diagrams if you plan on doing this.
