python 4230p for 99 nissan pathfinder.

How shuld I wire relays for Python 4203p on a 99 Nissan Pathfinder? Arm OEM alarm dissarm OEM alarm lock unlock Does horn needs a relay? Rear defoger does it need relay?ok let't start. (+) is positive (-) is negative.

Here is a link to the DEI wire guide info :  http://www.readyremote.com/main.asp?make=Nissan&model=Pathfinder

As shown, the Factory Alarm Arm, Alarm Disarm, Lock, Unlock and Horn all require a straight (-) pulse.  No relays required

No info listed for the rear defogger, sorry.

Soldering is fun!

Thanks in advance. In this link it says that pathfinder has (+) parking lights wire and (-)parking lights wire. So if I use (-) wire then I won't have to use relay right? Im just confused because even if it has a (-)signal wire, the manual says that I have to use a relay SPDT for locks, unlocks, arm,disarm,and parking lights (+). I have (-) wires on my passport and I didn't use any relays.ok let't start. (+) is positive (-) is negative.

I am not familiar with the Python 4203P and can not find an install guide.  Most vehicles have a (-) and a (+) Parking Light wire available.  You can use either.  It usually depends on the Parking Light output(s) of the unit you are installing and the ease of access to the listed wires.  Some units only output a (+) Parking Light signal and that is usually a 10A output.  

The typical (-) 200mA output from the Python unit is enough to drive most vehicles locks, alarm, horn and (-) Parking Lights.

ok I finished Installation. I tested everything. Worked fine. Then after a ride. I couldn't remote starter. Loks with ignition sometimes works sometime doesn't. Last night OEM alarm went off. Then at 3AM again something trigger the OEM alarm. I was using python without wiring arm and disarm wires with no problem. I think I'm just going to remove those wires and see what happen. Also before I put everything back together I was using bitwriter, Im just wonder if I change something that made remote starter fail.ok let't start. (+) is positive (-) is negative.

ok I found the problem. It was a defective toggle switch. I replace it and its working now. Alarm still trigger after I arm OEM alarm. It sounds like cranking time is too long. Can I use bitwriter to use volt detection instead of virtual tach?ok let't start. (+) is positive (-) is negative.

Minnesota???   Gets awful cold there. 

Run a Tach wire and change to Tach Mode.  Do the Tach Learn procedure.
