Okay so the guy who had my rx7 before the owner who sold it to me had one of those mobile cell phone things for the car in one of the storage bins. Its wires ran all througout the car the owner who sold it to me said I could take them out he just hadnt taken the time. So this past weekend I go through and get all the wiring out and stuff and some of the wires went up and behind the dash and it seemed they went up to where the radio and pioneer headunit were installed. I tugged on the wires from the cell phone thingy and they came out so I though nothing of it. Well this morning I go and turn on my car and now my head unit/radio will not turn on. I took it out and looked around and it had what I am guessing is the radio male end of a plug in it and then a connection with about 6 or 7 different color wires that were all connected. I noticed on the right side of the radio which is aftermarket if you havent guessed already it has a plug with prongs in it and a 10A marked next to it, so I looked around and found no plug like that. I did however find that two out of three wires on a different harness were broke. I am not very good with electronics and all these wires make it very difficult but shouldnt there just be a wire for power or something and how would removing the old cell phone thing take away my power. Sorry for the very long post but I hope someone can help. I could probably get pics up if needed.

basically all I need to know is what color wire provides power to the stock radio and I should be able to figure something out.

the 12V line in my '88 N/a is yellow. I imagine yours is the same, as im pretty sure mazda made them all the same...
