    Pulse start P1900

    Does anyone know how to hook the pulse start wire up to a keyless entry?
    I have a 2005 Infiniti G35 Coupe.

    Also if anyone knows where the ignition line not the acc line is in the g35?

    You can get wiring information at http://www.the12volt.com (among others).

    Any power line that is switched by the ignition will work for the IGN line for the P1900.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    Man you are fast with the reply I was under the impression that it had to be the ignition wire.

    4.2.1 What is a pulse?
    Voltage Pulse on Pin 1 of J1
    When connecting to Pin 1 of J2, the “pulse” must be a voltage that transitions from 0V to +V, and then transitions back to 0V. The SSC will wait (hang) if the voltage stays high without going back to 0V after the initial transition from 0V to +V.

    The value of the +V can be any voltage from approximately +2V to +20V. Typical voltages are +5V or +12V. The value of 0V must be below +.2V or open circuit (ie you could drive this input with a relay that momentarily connects to a +12V source and then provides an open circuit).

    Thanks for the help.

    Which is completely and utterly useless for a vehicle computer.
