door locks, 2004 maxima

hy guys i got a 2004 nissan maxima im throwing in a smartstart remote start now my question is how can i get a egative signal to hook up my lock/unlock wires i cant figure out how. i searched and all ive found was positive connections but the manual for the remote start states i wants a negative signal to the wire. pleae help

Most remote starts only have neg output lock triggers so what's your problem?
What has the positive outputs?
By the way a pair of relays is the probable answer.

Well thats my problem the wiring diagram I have from this site only shows a + wire. And my alarm diagram shows it needs a - so I'm trying to determine how I can find that wire and stuff. Thanks

What wire diagram are you using? Nissans have been - door lock for quite a while. Are you sure you're not looking at the unlock / lock motor wire?

Never seen a Japanese vehicle with POS locking so what alarm is it. Come to think of it I've never seen an alarm with only POS locking.

I think the wire diagram you have is wrong. And for reference, where did you find it so I know not to use it... haha. See my post above or howie's post for the correct lock wires.

PS Howie, where did you find the unlock / lock at the BCM? Readyremote only shows using factory arm / disarm. Granted readyremote isn't the best, but it hasn't steered me wrong yet...

HERE! Vehicle wiring
If you want I'll look at Directwire to confirm but Ready Remote is the same company.
Not doing this from memory because we haven't had Maximas or Camrys or bigger locally made Fords and GMs in England since about 03, killed off by Audis, BMW and Benz.
I think our OP is getting something a over t here.
Needs to tell us what alarm but I think since he's mentioned SmartStart, can we assume a DEI product?

lol. I trust you are right... not doubting that in the least. I was just wondering for future reference (since it seemed to have a little more information than readyremote).

Directwire gives ORANGE / black (-)lock and ORANGE / blue (-) unlock at the window switch.

Someday I wish to have access to directwire again... lol. But since I'm just starting out in my new business, it's just not worth the cost. I'd be paying out more than I was pulling in... lol.

Have you tested and verified any of that info because it's different to what we have.
If true look to the relay section, or I will show you how to flip (reverse) the polarity.

There are 2 ways to do locks on this car. The old fashion way would be to run into the door and grab the wires at the Window Switch Harness. the door panel is easily removed and there is plenty of room in the rubber boot between the car door and car body to run wires through. here is a YouTube Link showing how to take off the door panel. You'll also need to unscrew the speaker. You will be testing for the correct wires at the harness plugged into the Power window switch for ground while turning the key in the drivers door cylinder. These are considered the arm/disarm wires but they also control locks and domelight. You will hook up your lock wire from your remote starter to the arm wire in the car and your unlock wire of the remote starter to the disarm wire in the car. You will need to set your remote starter for "double pulse unlock" What happens is, with the first unlock pulse the factory alarm will disarm and turn on the domelight. The second unlock pulse will unlock the doors. You will not be using the arm/disarm wires off the remote starter itself, just the lock/unlock wires. Here's the info on the Arm/Disarm wires inside the drivers door at the power window switch:

Factory Alarm Arm     blue or pink/blue (driver door key lock)     -     power window main switch, white 16 pin plug, pin 4
Factory Alarm Disarm     red (driver door key unlock)     double -     power window main switch, white 16 pin plug, pin 6

Now for the second way to do this. Sometimes you can grab it at the inside the car. I have done a few 2004 maximas and sometimes this works, and sometimes it doesn't. It only take 5-10 minutes to try for the first timer. What I do is hook up my whole remote starter first and test that the remote starter is functioning. I leave the locks for last. I follow the instructions in the link I'm about to post and try it. If it works, I secure the wires and button up the car. If it doesn't, I take off the door panel and run the wires in. Here is the link and directions on doing the locks inside the car at the BCM courtesy of Chris Luongo, the pictures on the first page are actually of a 2004 maxima.

Factory Alarm Arm blue or pink/blue driver door key lock - power window main switch, white 16 pin plug, pin 4 Factory Alarm Disarm red driver door key unlock double - power window main switch, white 16 pin plug, pin 6 Nissan BCM Trick

On also, The wires you posted above for lock/unlock. The ones marked Positive. I have listed as the Door Lock Motor wires. You don't interface with those for your install. They are listed for different purposes.

Correct me if I'm wrong, but if he only connects the lock / unlock wires to the factory arm / disarm then if he starts it with the doors locked it will set off the alarm. The best way would be to set it on double pulse unlock, single pulse through the disarm wire, and tie the disarm and unlock wires together to the factory disarm. That way it will only single pulse the disarm wire to disarm the alarm when starting, and not fully unlock the doors.

Use THIS wiring Diagram as a guide. Always test your wires...

Nissan BCM Trick

Above link wasn't working... lets try that again

offroadzj, This car disarms with remote start. no need to send a pulse down the disarm wire to actually disarm except for when you unlock. Most Nissans Disarm when remote started. Actually, I think that they just don't go off when remote started... Only when someone opens a door. But what you said wouldn't hurt anything either.

That's good to know. I had a feeling that was the case, but I wanted to make sure (mostly for my own knowledge base.. lol)

ok so i got everything working except the unlock. for some reason its not working and its strait inside the door hooked up to the red wre. any suggestions guys

yes, you need to pulse the red wire twice to unlock. first pulse doesn't unlock. Look at your install manual under the programmable options and program for "double pulse" unlock. This way when you press unlock on your remote control, the remote starter brain will send 2 pulses automatically to the red wire and unlock the doors.

ok will try.... also idont know where to post this so ill post it here since it has to do with the car the side view mirror controls are on the lower dash panel of this car now while removing it all the wires came undone fom the plug does anyone know what wire go in what slots so i can put it back on?

another qustion towards the alarm it says i hae to pulse a wire in order to program the unit for the double pulse unlock how do i pulse the wire?

You are installing a viper VSS3000 right? You enter programming mode and change the programmable options using the valet button. You need to change the option in Menu 1, Option 5 to "On"

As for the power mirror wires, I don't know what wire goes where. You might need to find a Nissan Maxima forum and ask there. Unless someone chimes in here with the answer.

ok i figured out how to program it now i did that the module clicks 2 times so im assuming its double pulsing. now i have my unloc wire strait into the door onto the red wire which reads 5 volts on stanby and with the key turned in the door the voltage lowers so i guess thats the right unlock wire so i hooked up the unlock wire to it but it still doesnt work i went through ll the wires on the door switch harness and nothing unlocks the door. any ideas

Have you verified the unlock output to make sure its giving you a double pulse? Also, the best way to test the factory wire (and the output of the unit) is to connect the positive lead of your meter to a known 12v source and the negative lead to the wire you are testing. When activated it should show 12v on the DMM. You can also use audible continuity to test them.

This whole thread is becoming a damned if you do and damned if you don't situation.
Frankly, given the knowledge that the lock/unlock trigger wires were at the driver's door switch most of the "advisers here, Kenny, Kregg, Flobee etc. would have found and verified the correct wire within 5 minutes of removing the door panel.
Heck I've done this on BMW 5 Series and X5 without even removing more than the switch and releasing the lower half.
Problem: While advising rookies to use a DMM because frankly it's safer, most rookies don't know how to use it, get confused by the results etc.
It's much faster to use a bulb tester on virtually anything before 05 with positive (sorry) results.
Who gives a toss what voltage? If you ground two wires via tester and it gives you lock/unlock job done.
I never note the lock/unlock wire colours on say a Toyota, I just probe and very soon, job done.
Heck, shut all other doors, flick over the catch at the back of the drivers door and away you go.
As for pulling the wires off of the mirror switch, how the hell was that done considering these wires are in a plug.
You want to do a radio upgrade in a 30 year old Jensen Interceptor when you have to pull the front plate from the centre console complete with HVAC controls and ciggie lighter, all the wires are separate with no plugs.

ok figured it out apparently the module has to be programmed for single pulse on this car. everything works now.. thanks for the help guys.

and well yes i am an ammature therefore im on thisforum trying to learn from you guyas my proffession is an alecrticl tech for emergency vehicals. as i am new to alarm systems never done one before , but all said and done thank you for your help

You surprise me, I've done wigwags, lighting and horns for EVs.
My next son in law even designs the comms gear.
A lot of the work is similar such as understanding relays and diodes.
If you understand how to wire in that sort of equipment an alarm or R/S should be a doddle.

i guess i got lost with it being its my first one

You generally did OK, still can't work out how you lost the wiring to the mirror switch though.
A little secret, don't let it or us over awe you.
Ref. the mirror switch, it's possible to work it out with a multimeter.
Just remember that one wire either + or - will be common to all directions and you should have 4 more for each direction of the opposite polarity.
Two for the mirror fold unless there's a separate timer control.
Best bet is to try on a Nissan forum for a wiring diagram.
