Stereo Nightmare!!!

[buugiewuugie]

Ok I have a 90 240sx. I took the old radio out and the wiring harness was cut. but i was stupid and didn't look at what was hooked up where.

No I can get the radio to turn on. but nothing holds memory. the clock will work but when I turn it off it loses the time. the interior light will only work with the key turned foward. The radio won't remember anything either.

It wasnt like this before. I really need some help. there is like 5 red wires and 4 blue wires and I cant figure out where the hell they go.

Any help would be appreciated.

You need to find the hot wire in the harness that connects directly to the battery, that is your memory wire. Hook it up to the yellow wire on your head unit.

Go into our car audio forums and search for the S13 wiring diagram. Real easy, I had the same problem with my S13 when I got it. I HATE people who chop harnesses, lazy bungholes.

I'm moving this to the audio forum.

Mark knows his sh1t, hopefully he can help, and I'm sure he'd appreciate more traffic in the forums anyways, LOL

w/e you do dont cut the antennae plug, buy the metra adapter 40-ni10.

Your 12v constant wire is not hooked up to a constant source. Find the wire; on a 90 240sx it should be a red wire with black stripe going to the radio. Hook that up to the yellow wire from the new radio harness. This wire caries 12 volts to the radio even when the car is off. The radio needs constant power to save your presets, volume, equalizer settings, clock, radio settings, etc. Make sure you test the wire with a voltmeter first to make sure its the correct wire and that it is getting a constant 12 volts with the key off and on.

Honestly I could care less about the memory on the radio right now. It's more the seatbelts dome light and clock that I am worried about. none of them work! and I can't find a diagram for it anywhere.

You cooked a fuseable link or two. Check the underhood fuse box and look at the big funny looking fuses. Your problem should be one of those.

[adrianfromthecastle]

have you tried checking your fuses?

[buugiewuugie]

all the fuses are fine. and Everything works with the car turned on. but nothing works with it off. seatbelts dome light etc. it all work before i disconnected the wires.

i have similar problem, when i hooked up my cd player it was working fine..somehow it shorted....it took my clock (just numbers not light behind) and messing with seat belts (no longer opens with key off) ...all fuses checked (except big relay under hood cuz no obvious fuse pop)

[Tx-Sx-FS]

is there something particular that hooks the clock and radio together?? other than an interior fuse, what do the wires connect to??

[Tx-Sx-FS]

anyone..plz

my car is doing the exact same thing. i've got a 93' hatch with hicas and the car had no radio or speakers when i bought it, so now i'm ready to install new ones and would like to get everything resloved.i'm gonnna try to use those .pdf diagrams. hopefully it will work, i'll let you guys know how it turns out.

just switch the red and yellow and that will take care of the problem

Nope, nothing is holding memory including the clock, so switching wires won't fix it.
