Hey Dave, do you not have a light tester or DMM ? This will help you out alot and will only cost you about $ 4.00 for the light tester. Ground the light tester and probe the wires with the car off. When the light turns on, you have the constant wire located and splice into it and solder/tape together. If you still can not find it in the back of the deck, then run a new wire to the fuse box and find a constant wire there and remove the blade fuse and wrap the wire around the blade fuse and reinsert into the slot. Make sure that you fuse this wire as well when you do this procedure.
