viper 5704, 02 blazer, door lock, dome

Hello everyone! I'm in stalling a Viper 5704 remote start into a 2002 Chevy S10 Blazer and I need a little help with a few items:

1.For the power locks can I connect the alarm directly to the light blue and white wire at the BCM or will I need relays like the DEI451M?

2.Should I wire the OEM alarm disarm and arm wires or the disarm only?

3.If I wire the domelight supervision wire to the LF door trigger do I need to use a relay there or diode isolate. Would I be better off hooking up to the interior light by the steering wheel with a relay?

Thanks for any help, Jack.

you need 451 for doorlocks since theyre + plus put the GREEN/ black disarm wire to the light green vehicle disarm,..... all wires can be found in the large harness under drivers dash,... tach can be found in taped harness to the far right under drivers dash a little lower than the large harness sort of below center console but easily accessible from drivers dash      Item     Wire Color     Polarity     Wire Location 12 Volts     RED / white (50A)     +     ignition harness Second 12 Volts     red (40A)     +     ignition harness Starter     yellow     +     ignition harness Second Starter     N/A Ignition     pink     +     ignition harness Second Ignition     white     +     ignition harness Third Ignition     N/A Accessory     orange     +     ignition harness Second Accessory     brown     +     ignition harness Third Accessory     N/A Keysense     lt. green     -     ignition harness or BCM, lt. blue plug, pin B9 The BCM is in the center console, below the radio.

1) If the unit has dual polarity lock outputs (switch wires for positive output) then you can try connecting them straight to the light blue and white wires. But chances are you will need the 451m to control the (+) locks. 2) Do you have a factory alarm? If not then don't worry about it; if you do and you don't care about having it arm with the aftermarket remote than don't worry about the factory arm. Still connect disarm so you don't have to worry about the alarm accidentally going off. 3) You shouldn't have to worry about the domelight supervision. I'm pretty sure that the BCM will automatically turn on the domelight when the doors are unlocked. You can test it by watching the light when locking / unlocking the vehicle with the remote.Kenny

dome supervision wont work while vehicle is running when you unlock unless you use dome sup,... dei stopped using the flipflop +/- lock wires quite a while ago not sure why but im assuming to sell more productsGreenGables

Thanks guys, I have been pulling my hair out trying to figure these last few items out!!!!!!!!!!!

Ahhh... I wasn't aware of the domelight supervision being off when started. I guess a connection is required.Kenny

The reason they dropped the flip flops is they were sick of having to tell the fools to install conditioning diodes every time they fed to a processor or relay because of back feeds. And of course they sell more 451s

The install is going good and I am hoping to get this wrapped up tonight. The door locks worked our great using the 451m. For the dome light supervision I am planning on using pin A3 which is the gray/black wire on the BCM that controls the courtesy lamp relay. When I ground this pin I can hear the relay under the dash click and the dome light comes on. Is it ok to run the dome light supervision wire directly to this since it seems to just be a relay trigger or do I need to hook up a relay?

Run it directly but use a diode, 1N4004 in line, band towards 5704.
