Hi guys i'm in the middle of an M50 non-vanos conversion into what was a 1990 e30 316i. Both are manual and the M50 came from a 1991 e34 525i sport. I've been given a list of the functions of the wires for both the e30 and m50 loom to body plugs but on closer inspection the wires i have do not match with what i have been given in the list.
Heres the colours of the wires i have and the numbers they correspond to:

M50
1. BLUE/WHITE
2. BLUE/YELLOW
3. RED/WHITE
4. BLACK/BLUE
5. BLACK/WHITE/ YELLOW RINGS
6. PURPLE/WHITE
7. BLACK/PURPLE
8. GREY
9. GREEN/BLUE
10. BROWN/BLACK
11. BROWN
12. BROWN/PURPLE
13. GREEN/PURPLE
14. BROWN/RED
15. GREEN/BLACK
16. WHITE/YELLOW
17. WHITE/PURPLE
18. BLACK/YELLOW
19. WHITE/GREEN
20. BLACK
21. GREEN
22. GREEN/WHITE
23. BROWN/GREEN
24. WHITE/BLACK
25. BLUE

E30
1. BLUE
2. (EMPTY)
3. (EMPTY)
4. BROWN/PURPLE
5. BROWN/GREEN
6. GREEN/WHITE
7. GREEN
8. WHITE/BLACK
9. BLACK
10. (EMPTY)
11. WHITE/GREEN
12. BROWN
13. GREEN/PURPLE
14. BLACK/WHITE
15. BLACK/GREEN
16. WHITE/BLACK
17. (EMPTY)
18. BLACK/YELLOW
19. (EMPTY)
20. RED/YELLOW

Can anyone tell me what their functions are?
Many thanks

Hi thanks for the reply but pins 11 and 14 are still different colours between yours and mine, does this matter or is the function of the wire still the same? cheers
