OBC Upgrade - do I have the wiring??

[Jog5000]

Hi guys.
Was tinkering behind the dash today, and had a look at my obc - its the 7 button one - and I saw that there was another loom in there, with almost exactly the same connector as the one plugged into my current obc, except that it doesnt fit into the obc - do you think I might have an 18 button obc wiring in there??

The one in the current obc is white (i think, cant quite remember) and the other one is red.

Thanks

i would say no the full 18 button plugs are white and black and there female terminals i believe but it may be possible all the e36 are the same its just some have more options then others i have the 7 obc and all the other optionss so it may be possible but i doubt it
