Hey everybody. I am trying to put a CD player in to my 91 SE-R today. Its not working out so well though. the colors of the wiring in the SE-R doesnt make any sense. There isnt even a black wire for ground! if anyone knows the wiring schematic for the SE-R that would be greatly appreciated! thank you!

do you have the original wire harness? if so save your self some time and buy an after market stereo harness to connect to it. when i got my car it did not have it so i went to a wrecking yard and cut one out of an 89 240 and matched the colors. then i went to kragen and got a stereo harness to connect to my stereo. it will save you some time, especially if you get another stereo down the road.

that is the best way to do it. they cost like 15 bucks? o... and if there is no ground. ground it to a chassis spot (from the stereo)

test light would help you find what you need.
example:

with ignition off, tap wires with test light and find the one that stay on constantly. this wire will connect to a "orange" or "yellow" wire on the back of the head unit, should be labled contant or +12v). set that wire aside and turn on the ignition. tap wire to find a hot wire(to double check, with test light connected turn off and on your ignition, light should blink) and connect that one to a red wire on your head unit(wire may have tag that say: ignition or switched +12v). then you will have some wires left over those should be speaker wires. test all remaining wire to see if they are hot if not good. with a cordless drill battery find two of the left over wire that look like they match, ie: brown/brown with another color of stripe or dots and touch those wires to the +&- of the battery you will hear a "bump" find that speaker that is going "bump" and label wire for future referance. if no bump then check other wires (disclaimer:"do not" touch any hot wire with battery)untill you have found the speakers and then connect those wires to the appropiate wires on your head unit.

all this for a $2.99 test light, a battery and 30min.

the wires dont match up?? all you need to worry about are yellow=constant power; red=switched power; ground to chassis; and then there are 8 other wires-2 or each speaker one negative and one positive... if you really wanna do it w/o a harness, just test 'em. use the right front wires from out of the cd player, and start tapping a pair of speaker wires that come out of the sentra, and see if youre right. if it comes out of the wrong speaker, just remember what those 2 do, and go to the next until you find the right ones. once you do, move on until theyre all hooked up.

There was no ground in my 94 Limited Edition. I had to ground it myself. I forget where I put it though... Sorry.

to the best of my knowledge you must gound it yourself. anywhere you can find metal that is out of the way will sufice.

No ground? hrm...

Oh yeah, on our cars (at least my car, lol) you need an antenna adapter b/c the antenna must carry power - my cd player works only when the antenna is plugged in, but gets no power w/o it - but in my Corolla I ran it w/o the antenna for about 2 months before I realized it wasn't connected (say what you want about Jensen - the tuner on the CD330X is one of the best I've ever heard - and I got the deck for $50...)

And if you haven't cut your wires, go get a wire harness now - I cut the wires in my Corolla, and even though the deck worked, it was blowing fuses like crazy, so I had to resort to the worst thing possible - pay a shop to repair my mistake! I paid $15.99 for my wire harness & $14.99 for my antenna adapter, not bad considering it was the only place in the area that carried the parts for a B13.

I've seen sites on the net that have the wiring diagram on them. I can't remember but look up nissan and wiring harness for stereo. You should get it.
