1998 nissan maxima factory disarm

you should have a factory disarm wire off the alarm itself (and if not then you can use the unlock wire off the alarm) to disarm the OEM alarm from the prestige. if you have to use the unlock wire then you must diode isolate if from the unlock wire in the vehilce. the wire you are looking for is the alarm disarm which is GREEN/ YELLOW and it is being listed in the smart entrance control unit which is

"The smart entrance control unit is located to the right of the steering column. It is black or blue in color."

that is the note from directechs. it is a negative trigger by the way. hope this helps and good luck!

if both are a neg trigger then here is how you would wire it

87 ground

**87a Insulate and left blank**

86 fused +12volt

85 trunk release output from 997 alarm ( i think this wire is a Neg 300 mAh output)

30 to trunk release wire vehicle (with diode)

30 to OEM disarm (with diode)

now the 87 and 30 in this application are interchangable so if you have it backwards from this don't worry. i just use a standard way of doing it so i can remember it later if i have to trouble shoot it or something. i hope that gets you fixed up but if you have any other questions holla and i will get back to ya. good luck.
