My buddy who had a 318ti from around the same time was telling me I didn’t need a wiring harness to install an aftermarket headunit in my car; that at one point there was some sort of standardization of the plugs

anyjuan?

As mentioned on AIM I didn’t install mine in the M3, but a quick google search returned that it does need a regular adapter harness to plug into the stock harness.
