Adding keyless when it was not factory
I have searched plenty but can not come up with a definitive answer, many threads seem to touch on it but no solid solution. I have a 98 SE that does not have keyless, there is no box in the trunk near the antenna but the wiring and plug are there. There is no relay near the trunk latch either. To have basic keyless do i just need to buy a keyless module for the trunk and a remote?

thats weird. i was pretty sure every 4th gen came from the factory with keyless entry standard. my 95se didn't come with a remote when i bought the car last year but i bought one and it worked. Could the box and relay have been taken out maybe? I would think that those and the remote would be all that you would need. I think anything from a 97-99 should work for you.

my 96 has electric everything but it didn't have the security package or whatever. I do have an aftermarket alarm on it but it only locks/unlocks my doors. I havn't tried to hook up the trunk yet or the horns.

Well. my 99 SE came with the secuirty light fo sure. Tried programming method(key in key out), no lights flashed. Di some research looked in the trunk for module, wasn't there. Decided imma try find a module and put back there. The next thing i found out was that i had to find two wires back there that wud fit to the module and one for the antenna or else wouldnt make sense. Couldnt find the wire for the module. Looked behind the pillar in the back of the car, didnt see it, thats when i stopped and decided to stay with the keys opening the doors.

if your car has the security light in the dash then the car is prewired and you should have everything there. its also possible that someone did repairs on the rear right Q-panel and did not reinstall the keyless entry computer. if the wires are all there, just get the keyless entry box and relay and try programming the remote. should work.
by the way, i have the relay and that keyless entry computer for $20 shipped, pm me if you want it.

my car does not have the security light but the plug is there behind the block off where it belongs. I also found the plug for the trunk latch. It looks like the only wiring I am missing is the antenna. Module and relay are coming (from nsnrider)

All 4th gens were prewired for a few things, like power seats, keyless entry/alarm....It all just comes down to getting the stuff to make it work. It looks like your on the right track. The box and a remote is what youll need. Maybe if you want you can get a security light.

Not entirely true. I have a 95 gxe, manufactured in 94 so it was one of the first 4th gens, I added dual power heated leather seats to it. Originally the car was driver pwr and passenger manual. I removed the carpet to look for wiring for the passenger power but had no luck. I was forced to tap into the driver power and wire to the passenger seat.
I have heard that all 4th gens came pre wired for fogs. I added fog lights and those came pre-wired the empty harnesses were tucked behind the front bumper cover. However I have heard people claim their car did not come pre wired for fogs.
It seems that a majority of cars came pre-wired for these common accessories but no necessarily all of them.

Well I got my module and relay today which brings up a few questions. The relay I got is blue and in the relay box under my hood there are no empty slots and in the slot marked "anti theft" there is already a black relay. The only difference I can see in the 2 is the interlocking, one is NO one is NC. Is there a way to test if the system works without a remote? I plugged the module in, locked the doors with the key, reached through the window, unlocked the door and opened it but nothing happened. I just have the module laying in the trunk as I didnt figure it would be grounded through the body.

My question is...can i test the module before I purchase a remote? I tried the program sequence also but could not get the lights to flash either. (I dont have a remote but I thought that if I could get it into programming mode I would at least know it was functional)

There does not really seem to be an effective way to test the remote system without using a remote. Maybe you can borrow someones? From looking at the electrical diagram in the FSM it appears if the system has the multi remote relay, multi remote unit and the wiring it should work. I'm really surprized someone has not tried this before you.

Very good point, may take me a while but I'll see if I can figure it out.

EDIT: I just checked and I have 12v to the module.

I have an open slot but there is no plug (unless it is taped down under the others like all the other security wires have been) can you tell me where the relay should be in relation to the others?

Insert and remove the key from the ignition key cylinder more than six times within
10 seconds. (The hazard warning lamp will then flash.)
Above is from FSM, Hazard warning lamps cannot flash without the Multi Remote Control Relay installed. I'm having trouble finding it's location, appears to be somewhere other than most relays.

Yes that is the Multi control Relay back there. You need that relay, check out the link provided. This will cause blink of warning lights. Still cannot really check the system without a remote. Borrow one. I'm not certain it will work but all the brains for the remote are in the remote unit you installed. The antenna is there also. I believe when you do the programming of the remote you are communicating with that box. Good luck let me know how you do.

Thank you for the help, I should be able to make that relay as I dont want to wait for it to be shipped just to verify everything works so that i can wait once again for a remote. In the fsm it does not show the antenna but on the module there is a shielded connector for one. Any ideas?

My feeling is it should flash with that relay properly installed that will tell you it is ready to be programmed, I'm not certain kind of learning this system on the fly.

Nissan used 2 different rear windows. One has an antenna built in for the keyless entry and one doesn't. Does yours have it built in? The keyless system will work without the antenna hooked up but the remote has to be within a foot of the module.
