2001 Nissan Pathfinder SE remote start

here ya go, hope this helps. if its your first remote start, and you do not have too much alarm experience, you may want to have a pro do it, because this car is a little harder then a basic install. but, if you like doing stuff yourself, here it is:

wire               color               polarity                  location

12v              WHITE/ green         +                      ign.  harness

starter      BLACK / YELLOW           +                      ign. harness

2nd starter  RED / black            +                       ign harness

ignition      BLACK/ white           +                      ign  harness

accessory  WHITE/ blue         +                         ign. harness

2nd accy.  RED / yellow            +                        ign. harness

lock wire   yellow                     -                      security module  (between steering column and fuse box)

un lock wire    light green        -                           security module

parking lights       blu/blk or pink/blu or pink/blk           +            fuse box

tach wire  WHITE/ green                    ac                                   ecm (right of steering column)  do not un plug it 

brake     GREEN/ YELLOW       +                    brake switch

immobolizer bypass -  you have a chip in your key that needs to be bypassed to remote start, use a dei 556u  or its equivalent.                       

I also have a question about the '01 pathfinder.

Does any one know if there is anything special I should know about the power locking system in this vehicle. I have a freind who has this vehicle and the guys who installed his remote starter said they couldn't do his locks. So he wants to come down and get me to do it, but I have never done a Pathfinder before and it kind of worrires me that the other place said they can't do it.

All the wriiing diagrams said that they are just negative wires, just want to know if this is true, or do they need a resistance or something?

According to the wiring information, you need to use Door Lock and Door Unlock wires. These wires will also arm and disarm factory alarm. The wires are:

Door Lock - Yellow (-) - pin 41 @ SECU (Smart Entrance Control Unit) - between the steering column and the fuse box.

Door Unlock - Light Green (-) - pin 30 @ SECU.

Door Trigger for driver door is GREEN/ red in pin 29, the front passenger door is yellow in pin 40, and the rear door is RED / blue in pin 28. Use all three and diode isolate each. (use these only if installing alarm, you will not need it for remote starter)
