Help With Alarm Install R33

[Keeper]

Hi,

we are slowly repairing the damage done to my flatmates car and have start the install of a Fusion F3500 alarm.

Can someone help me with the following,

is it a - pulse or + pulse central locking system? can i wire off the control unit located above the ECU? or off the door wires themselves? we have the whole dash off at current, there is a single black wire with orange dashes hanging from the plug on the bottom of the assembly, but it has been taped/glued over at the other end so can not locate where it went too, te car did previously have an alarm in it

if i get the door input - off the wire for the left door sensor, will opening the right door also trigger the sensor or is there a relay further up i should take it from???
