Hello so I have a 2000 Nissan Maxima automatic with a 3.0 engine that somebody had spliced cut jumped and completely mangled up the wire harness under the dash to the point it was a hazard. As the person I am I could not have that in my vehicle so I went ahead and went and bought a brand new wiring harness for it I then removed the one that was cut spliced and hacked up and replaced it with the brand new one I hooked everything up the same way that it was and should have been as well as put a new ECU in it you know the one that goes in the center under the heater controls and stereo so I had to reprogram it which I did and everything started to work fine but I did not have anyone to check the lights for me and they are not working but the brake lights work the reverse lights work but the dash lights and the running lights do not work however the front running lights stay on at all times and there is something under the hood near the battery that sounds like it is still running something electrical not sure what it is not sure what I have to do but maybe you could help me with this I am very familiar with cars and electrics but this one has got me stumped.

Here is a screen shot of the dash lights while the car is off when the car is running the lights on the right side go off and the left ones stay on and the airbag light flashes. The video is the sound coming from under the hood by the battery.


The first thing to do is to check all of the fuses.  The tail/park light fuse is in the underhood fuse box. It should be fuse number 60 and it is a 10 amp fuse. If that fuse is blown, missing or not powered at all times the park/tail lights will not work and as a consequence neither will the dash illumination lights.

After you have confirmed that fuse is powered and properly installed turn on the park/tail lights and listen for the click of the tail lamp relay. You should be able to turn the switch off and on and hear the clicking of the relay. The relay is inside relay box #1 under the passenger side of the hood.
