hey wats goin on i have a 99 si the person before cut the radio connector off the main car harness. i wired up 2 difierent radios and all i get is the noise when ur loading a cd and the screen lights up but no display wont play cds. it will suck in and eject cd but wont play some help please

 

Check for acc. power, the yellow/red lead in the OEM radio harness should have 12V+ when ign. switch is in acc. and run.

You have constant power, white/yellow, we know this because a disk will load and eject.

Fuse for radio acc. power is in the under dash fuse box. 94

 

ok i only have power to the yellow/red wire i dont have power to the white/blue wire or any others. i have power and i have a good ground. the cd player gets power but no lights

 

The 12V+ constant may be white/blue instead of white/yellow, [depends on where dash harness was made] and should have power at all times, it is the constant power for memory in stock HU, fuse for it is normally in the under hood fuse box and is probably a 7.5A.
The red/black lead is illumination and will have power when park/head lights are on, if you HU does not have an illumination lead, [orange] cap off the red/black lead, also if you have a red lead in the cars radio harness, cap it off, it is the ground, [from dash light brightness controller] for the dash lights, if it "shorts" to ground you will have no brightness control of your dash lights. 94
