2001 maxima factory disarm/rearm

Yes, what he said. I sure hope you're testing all of your wires. The best thing on that car is to have the kick panel removed, and unwrap the harness that goes to the back of the car. Parking lights and brake are both in there. If you can make your connections a little bit higher in the kick panel, that'll be more reliable, in my opinion. You can make the connections along the doorsill where the harness runs to the back of the car, but it's a little more vulnerable to moisture there, if the carpet should get wet during rainy/snowy weather.

Thanks guys, thats exactly what i ended up doing. the only other issue is that i recall Chris stating that i should connect the rearm wire to the driver's doorpin, if i use the auto headlight feature. It was here: "--If the customer uses the "auto" feature of the headlight switch, connect your "rearm" wire to the driver's doorpin wire. The autolights won't time out until the car "sees" an open door...........if you don't hook it up, and the customer remote starts the car at night, and shuts it back off by remote without driving....the lights will stay on and drain the battery." I discovered that the lights stay on after the car stops RS even when just having the regular (non-auto) headlights turned to the on position. So I guess i must connect the rearm to the driver's doorpin. But, will a diode be needed for this connection?

A diode will only be necessary if that rearm wire ends up triggering the 5900's alarm.  To test:

Connect the factory rearm (-) output from the 5900 to the driver's doorpin wire. This connection should ideally be at the same point that you have connected your door trigger input.

Arm the 5900. Wait 10-15 seconds and remote start. Once the car is started, shut it down with the remote(the 5900 needs to still be armed at this point).  If the alarm doesn't go off, no extra diode is necessary.

If the alarm goes off there - you'll need to cut the driver's doorpin wire and insert a diode so that the following are true:

Cathode(striped) side is facing the door pin switch, anode side is facing the SECU.Door trigger input for the 5900 is connected on the cathode side.Factory rearm output is connected on the anode side.
