Hi everyone,
so i have a 90 525 and this years stereo wiring is a bit different than the newer ones, as in there is no harness for the head unit. So I am guessing that the amp in the back has different pins. I was just wondering if someone has added an aftermarket amp to their 90 or older and knows the pins or if it is the same as the 3 series pins on bmwe34.net. thanks.
