I am trying to install my viper 5900 into my civic si and I have a few questions.

1. Do I hook the H2/4 GREEN / WHITE (-) factory alarm rearm with the door lock GREEN / WHITE (-) of the keyless module together? The manual says to use a relay, but doesn't the car already have one?

2. Same as above only for the the H2/6 factory disarm. Do I hook it up to the door unlock GREEN/ orange (-)?

3. Where do I find the trunk sensor wire? And what color is it? And how do I hook it up?

4. Finally, will the dei 508d work well enough as a motion sensor? Rather than going with the crime guard au94t?

Thanks in advance.
Dave

1, 2: Using a relay provides a better ground to the wires (arm/disarm) than the 250-500mA (-) charge that the alarm puts out .. and oftentimes if you just connect the (-) wire from the alarm directly to the honda arm/disarm wire it doesn't always arm/disarm properly and the alarm can go off when the car is remote started or unlocked w/ the Viper.
