V70 wire harness interior

I have a question once to the electrical experts. My dashboard has clapped like hell, got me a used one and installed this, it was complete so with the entire wire harness that goes down in the footroom to the large central plug. The installation or removal of the dashboard has worked so far, now to my actual problem. The dashboard comes from a 97 or 98 v70 my v70 is bj 99, I did not convert the wire harness of course because I have the vö I have llig splintered, now at the first start 9 errors from ETS to ABS and general communication runs of course also accordingly, no ventilation, no speed signal etc etc. Can please confirm to me that you can not really be so stupid !!!! At the latest with the E – throttle flap I would have had to remember that the wire harness also has to be rebuilt. If I just think about it again everything will be bad for me.
