I currently own a 1989 780 Turbo. I discovered a loose connect in the 6 pin DIN connector on the back of my Volvo TD-6146 radio. I was trying to carefully take apart the old DIN plug, but then all of the wires broke off at one time. I know the orange wire goes in the center, but other than that, I’m stumped. The wires that were connected were black, orange, blue, red, green and the loose silver wire wrapped around the outside of the wires. Being that hindsight is always 20/20 I know I should have been a lot more careful. (I’ve been kicking myself for that for the last month.) I have searched online, bought schematics on eBay, but none match my system. I’m inches away from ripping out the entire system and upgrading it to a new one with a CD, but I know that I really should keep it as original as possible. The system is the standard Volvo 780 setup that includes both front and back amps as well as the equalizer. If anyone can help me find the correct way to rewire my new DIN, I would be very grateful. Heck, if you even live around the Atlanta area I’ll buy you a few beers! Thanks
