    I would just recommend mounting it to the dash frame where the under dash screws into.

    Ok, I'm stuck.

    Got most of the wiring done, and am at the testing stage.

    I'm having 2 problems. One is that the door locks do not engage/disengage with the arming/disarming of the system. Looking at the manual, the output wires for locking and unlocking from the viper unit are small, and do not supply the 12VDC that I need at the BCM where I hooked them up. They are hooked up to the first (left side) BCM harness. the unlock output from the viper to the white (A3) wire on the harness (labeled: Power Door Lock Relay Feed - Unlock Coil). The Lock output is connected to the light blue (A4) wire in the BCM harness (labeled: Power Door Lock Relay Feed - Lock Coil)

    The only other possibility I can see is on the second (middle) BCM harness, there is a wire (A4) labeled: Power Door Lock Relay Control - LF. Any help here would be great.


    My second problem is with the remote start.

    I've hooked up a tach signal wire, as well as changed the engine checking method and still have the same results. The truck will crank, and just as it starts, it dies. I get the same result if I turn the key on and try to activate the remote start. If I use the key to start the truck, it starts right away and runs just like normal.

    The only thing I can think is that it has something to do with my Remote Start harness. My wiring is as follows.

    Viper---------Truck
    H3/1 (PINK) Ignition 1 Input/Output----------A2 (PINK) Fused Ignition Positive Voltage
    H3/2(RED/WHITE) Fused Ignition 2 / Flex Relay Input 87-----------A4(ORANGE) Fused Battery Positive Voltage
    H3/3(ORANGE) Accessory Output--------------(ORANGE) Ignition Positive Voltage
    H3/4(VIOLET) Starter Output-----------------------Truck side of starter crank wire
    H3/5(GREEN) Starter Input-------------------------Starter side of starter crank wire
    H3/6(RED) Fused Ignition 1 Input-------------------B1(RED) Fused Battery Positive Voltage
    H3/7(PINK/WHITE) Ignition 2 / Flex Relay Output------------(ORANGE) Ignition Positive Voltage
    H3/8(PINK/BLACK) Flex Relay input 87A key side (if required) of Flex Relay-------------Not Connected
    H3/9(RED/BLACK) Fused Accessory/Starter Input--------------B1(RED) Fused Battery Positive Voltage

    Also related to the remote start

    H2/9(VIOLET/WHITE) Tachometer Input-----------------(BLACK/WHITE) Injector Signal (I wired this to the signal wire of one of the fuel injectors, just not sure which number the injector is)
    H2/17(BROWN) Brake Shutdown Input-------------------Wired to brake pedal switch (gets 12V when the brake pedal is pressed)
    H2/18(BLACK/WHITE) Neutral Safety Input---------------Common Ground

    I've been using the install manual plus the following link to determine some of my connections.

    Also, all connections are soldered, so everything should have a good connection.

    Any help would be great, I'm gonna keep playing with it today, and see what I can come up with.
    Thanks

    PS, can anyone tell me where I could find the controller for the factory alarm? As of now, there are 2 wires on the viper unit ( oem alarm disarm output and OEM alarm arm output) that are not connected. The guide shows using a relay with each wire to send the 12V signal to each wire (the disarm wire and arm wire) of the factory alarm system. I just haven't found where to hook those up.
