phoenix digital 175 alarm/remote start

Are there anyone installed PD-175 http://phoenixdigitalaudio.com/accessories.html,It is need to connect red wire form P7 remote car starter to Oil sensor signal wire on vehicle , 12 volt when vehicle start cussessful. I don't know how to find this wire on nissan maxima? I don't think it is tach wire.Please help me out if you canThanksAnthony Nguyen

Oil sensor should be on side of motor, screws into motor on the side with like 3 wires coming out. Not sure which wire you need but you can use a volt meter. Are you sure you need this hooked up?Gary Kline

yes this wire has to be hooked up in order to begin the startup sequence, and - it must read ground (low) to start the motor, and hot (high) in order to stop cranking the starter.  as i've already said in the other post, the solution is rediculously simple enough that anyone with basic auto electrical knowledge should have been able to figure this one out.... hook that red wire to the alternator field wire.  the field wire at the alternator will read low when the engine is not running, and high when it starts.  i've done this with 100% success on these same alarm systems numerous times.   another note you should make sure of - if you intend on hooking this to pin switches that are isolated from the actual dome light circuit for one reason or another, make sure you tie a 5k resistor to the wire that is connected to the 12v+, otherwise the alarm will false trigger showing the door being opened (normally, when connecting to the pin on grounding door pins, the wire is hot when the light is off, due to the fact that there is power on the bulb, with no ground - the 5k resistor simulates the alarm being hooked to the dome light and stops false indications)  - also, if you want to hook up extra hood switches, etc - just connect the door pins thru a diode, and that way the hood pin can't turn on the dome light when the hood is raised.  any regular type like a 1N4001 will work fine, just about any standard barrel diode will suffice also.
