i need help...
where can i get a free diagram of the stereo wiring for a 1989 lx???
there's no plug on the end of it, and it seems to be having problems!
when i turn the stereo on, it works fine, but no memory.
both power wires only come on when there is power supplied by the ignition. when i turn the lights on, the stereo goes out. ive installed many stereos, and never run into a problem like this. can anyone help me????
oh yeah, no dome lite either, but it works when i hook it to a speaker lead!!!
WTF????

The lack of memory sounds as though who ever hooked up the stereo did not run the constant power wire correctly. It appears as though they put it on a circuit that is activated by the ignition.

Is it aftermarket, or the stock stereo? If aftermarket, I would re-wire the entire thing properly. Hook the yellow wire to a constant 12V source, the red to a ignition source, the black to a ground, and then just wire the speakers accordingly. If it is stock, I would replace it with an aftermarket head unit. If you are just looking for some tunes, a decent cd/mp3 player can be bought for cheap.

I wouldnt run it directly to the battery. Find a fuse in your fuse panel that has constant power, and use that for your 12v constant power.

They're right, i had the same problem when I got my 92 LX and it was a quick fix, reversed the way someone had hooked it up, they had the 12+ to the ACC wire and ACC to the 12+, exact same problem with cutting the lights on and no memory, so that should fix your problem. Tony
