Stereo Wiring.....

[89 240 SOHC]

Putting a Sony Deck into my 89 240SX What wires from the car are power, ground etc?

Buy a test light (like 3 dollars from a parts store) and just poke around untill you hit a hot wire while your key is on the accessories position. That will be your power wire. The deck grounds through the antenna if i remeber correctly (i installed my deck over a year ago).
