Aftermarket stereo problem

[Daiastacio]

I am in the process of replacing an old alpine stereo for a newer pioneer stereo (MVH-X380BT) in my 1995 Lexus ES 300. I connected the wires correctly but I have no power in my stereo, what should I do to start troubleshooting?

Daiastacio,

 

On the wiring harness to the radio, check the pins with a test light, the red and black. Test light should go on if the ignition is on. If not, check your fuse panel for any listed as radio/amplifier. If you have power there, then the problem is in the connector at the radio, or the radio itself.

 

Basically test to make sure you have 12 volts going to the radio when the ignition is on. If there isn't, you have some searching to do.

Are you sure you have the correct Pioneer to Lexus sub harness, because if the wire colours don't match on both sides of the connectors the radio won't work.  Good Luck!
