Need Help With Deck Wiring Diagram.

[ice-burg-slimm]

Does any one know the wiring diagram for a 95 sc300.The diagram that came with the single din is not working./

get a voltmeter and probe the wires for 12v with the key in off position and again when the car is on. I bought a metra kit for my 99 sc300 and none of the wires matched either.
