    Need Help! Installing ECU for 90 325i

    I am a noob in need of assistance with hooking up the carputer to my wiring harness and other associated plugs in the glove box. I'm at a loss for what some of these connectors actually go to. (pics below)

    I swapped a 1990 m20b25 into an 86 325e and bought the corresponding harness and ECU. I was wondering if I need to get the ECU reset or reflashed before hooking it up.

    And these are some plugs that I found on the glove box that might be important

    Any help is appreciated and if there is already a similar forum that would be useful to my project i'd appreciate your URLs as well. Thank You!

        Well that's one down. Don't think I'll even be worrying about the charging port. Does anyone know about the 4 miscellaneous ones in the first pic? Thanks for your help!!
