Ive put a 87 celica single din radio into my pickup and I noticed there's a midi style plug on the back. This was used for equalizers and even tape deck add ons. I'm wondering what the pin out is and possibly use it as an input for bluetooth? I haven't been able to find anything about this plug. Images are just for reference to what I'm talking about.
