If I have the negative and possitive still connected to the battery and a ground and power touch on the radio harness, is my radio shorted out forever or is it just a fuse that blows?

How do yo hook up a boss stereo to a 1994 nissan pickup 4x4 2.4L? need to know what wires from the stereo go to what wires on the truck!


If there's a harness in the dash still, do not cut it off! The easiest thing to do is get a wiring harness that will connect to your Boss radio and then plug right in. You can get them from Amazon or your local electronics store like Best Buy. You can sometimes find them at WalMart as well. The benefit of going to a place like Best Buy is that they have an installation bay with trained techs so they can ensure that you have the right harness. The colors on this harness should match that of the Boss stereo and it's just a matter of soldering/crimping them together.

If the harness has already been cut, its a little more difficult cause the factory wiring doesn't match what's on the Boss. I found the wiring colors for a 94 Pathfinder here but couldn't find any for a 94 Nissan Truck. They should be the same/similar but either way your should still check the ignition/switched and constant power wires with a multimeter before connecting them to the new radio.

For the constant, you can get ground from any piece of metal inside the dash, touch it to the wire the suggested in the diagram. The meter should show 12v or just under. Do the same for the ignition/switched, you shouldn't get any reading. Turn on the ignition and it should go to 12v or just under.

For the speakers you can check the pair with a 9v battery. Take the two wires for lets say the left speaker, blue/white and blue yellow, and touch them to the positive and negative terminals of the battery. You should hear a pop from the speaker. If you don't most likely the wiring is different from what I have listed below which is fine.

After figuring out the which wires are the powers and ground you can basically take one wire and put it on the positive terminal of your 9v battery. Now go through the rest of the wires and tap them one at a time to the negative terminal. Do this until you hear a pop not the wire colors and which speaker made the noise. Now move on to another wire and repeat.

The downfall of doing this is that it doesn't tell you polarity. After you finishing connecting the radio to the in-dash wiring turn it on. Listen to the sound carefully. If it sounds tinny one or more of the speakers polarity are incorrect. Try to determine which speaker/s sound tinny and reverse there wiring. Check again and hopefully everything's sounding good.

Somebody attemted to install the radio and now it is draining the batery


You'll have to open the dash and get to the radio wiring for these solutions.

Solution #1: Sounds like the ACC lead (yellow) and the Power lead (red) are both connected to the same power wire.

If the radio is able to be turned on and played while the vehicle is off and the key is out, then both of these leads have been wired together. That's bad. There are two different leads for this...one is for power when the vehicle is turned on to operate the radio/CD, and the other is a trickle to keep station presets, personal settings, and clock accurate.

These wires need to be separated.

Solution #2: It is possible that the ground wire was not connected correctly and needs to be connected securely to the ground wire. Does the unit get hot? If so, there may be a grounding issue that needs to be taken care of or run the risk of damage to the radio and possible the vehicle.

Solution #3: Inspect the wiring job. Are the wires twisted in-line or are they twisted and poking up like small antennas? Are they wraped securely with tape? Were thread nuts used (very bad)? Are there any exposed wires at all that you can see in the wiring job? Any exposed wires can cause shorts in your electrical system and drain your battery. You will need to get some electrical tape, shrink tube, or in-line wire clamps for the job.

For all of these solutions you will need to get a wiring diagram for the car, the radio, and the wiring harness that was used. Trace all the leads and make sure they are all correct. Usually you will see them in two blocks, one for power and the other for speakers.

Power: Red (positive charge), Yellow (AAC), Black (Ground/Negative power). You can also find a dimmer lead and a power antenna lead here. If you don't have these capabilities in the vehicle, cap and ignore these.

Speakers: There will be a solid color for one wire (the positive) and the same color with a stripe (negative) for each speaker.

Most systems will print the positive/negative and which speaker they go to on the wires themselves.

Be sure to thank the "somebody" for this stellar install job. I hope you find the problem and get it worked out.
