CarNetix CNX-P1290 V1.0 Installation ManualStep 3. Run the Ignition WireAfter the ground connection is installed, you will need to find the “ignition” wire. This wire istypically yellow and provides +12v when your ignition switch is on. Connect to this wire either bysplicing into it and soldering the 3 wire-ends together, or by using a “T-tap” splice connector.You may have to search a bit for the ignition wire, but it can typically be found connected to yourradio or head-unit. It is very important that you find the correct wire since the CNX-P1290 will notfunction if this wire is not connected or working properly. It would be a good idea to check, withyour DMM, that +12V is indeed present when you turn your ignition switch on, and that it goesaway when you turn it off.Once you have located and spliced into the ignition wire, you will run this connection to theYELLOW (pin 2) wire on the input connector (J1) of the CNX-P1290. One option (show in Figure 5above) is to put a SPST switch in series with the ignition wire before it is connected to the CNX-P1290. This gives you the ability to turn off the CarPC (or prevent it from turning on) regardless ofwhat position your ignition switch is in.Step 4. Connect the output C134 Power CableThe optional case power cable kit includes a power cable (Figure 3) with the appropriate plug toinsert into the existing rear-panel-mounted case power plug. This means it is not necessary to openthe case to connect power. Simply solder this power cable to the (+) RED and (-)BLACK wires onthe 6-Pin output power connector (J2) of the CNX-P1290.Figure 6 Case Power Cable (Part of CNX-CA-C134)- 16 - |
