So is the wire coloring for 1995 nissan d21 accurate by Skittle.

No clue..... but he's not been here, since you started! Maybe someone else can answer.

Thinking about it..... you got a meter? Check the power leads. You should be able to figure it out. DC and GROUND are all that's needed to power on the unit. Checking speakers, after this, is easy.

Best bet is to get out a meter and start probing things.

Wire colors posted by Skittle are not correct, first there is NO ground in the stock harness. Colors below are taken from the factory service manual.

Switched power ( on all the time) is green with white stripe
Constant power (on with the key) is red with green stripe

Left door speaker positive is Brown with White strip
Left door speaker negative is brown

Right door speaker positive is black with white stripe
Right door speaker negative is black

Remember , there is NO ground in the stock harness, ground radio to metal near the radio, do not rely on the antenna to make a ground

As was said already if your not sure, all you need is a test light, find the constant and switched power wires, than when you remove the existing speakers you will see what color the wires are, or you can run new speaker wires. If you buy a harness ( if your stock plugs are still there), you can just match up the colors to the aftermarket radio if you are installing one.

Illumination shows 2 wires in the service manual not sure why there is 2, one is pink with blue stripe, the other is Pink with black stripe

Whoever bought the truck new put a stereo system in with a amp and cut the harness. When the truck got wrecked he must have put another radio in and sold it.I got tge truck 17 years ago and threw a cd in it but without switched power. I'm tired of not having presets. Plus he originally had it hooked to the cigarette lighter and each time you hit the lighter with the stereo on it blew the fuse.

If you do not have, or can not find a switched power wire near the radio it is easy to add one using a fuse tap at the fuse box and just run a wire over to the radio.

According to a hard body I've wired it. He has constant and switched hook to switched. I hooked them up correctly yet I don't have constant. I programed radio station, turned ogpf , removed key reinsert and turn on and have lost the preset.

Rebelwork · 02-08-2021, 07:47 PM

So we had a switched and constant tied together going to a switch wire. Now I have separated switched and constant and yet constant doesn't work.

ahardb0dy · 02-08-2021, 08:04 PM

Run a new constant wire to a fuse, or just to test, run the constant from the radio to the battery than program stations and shut the truck off, make sure it's a wiring issue and not a radio issue.

I had a radio in one of my Nissan's run to fuse taps both constant and switched for a while due to getting noise, no problems doing it that way, just use a fuse that doesn't have a big load on it.

The radio has the wiring identification on top of the radio.

Red---- switched
Yellow---- battery

I ran yellow direct to battery and didn't keep the pre sets...
