81 Civic Stereo Wiring
 

I've been searching around and can't find the wiring diagram for the stereo harness on my 1981 Civic Wagon. I know that a lot of honda's share the same wiring but I'm not a fan of just hooking up and testing electrical stuff on a car this old with a deck that I paid over $300.00 for. Anyone know for sure what the wiring codes are?
