Read up on the relay section on this site....loads of info on a great little gadget, that makes life easier doing installs. 
The wording on the install sheet about the "imobilizer"....it's total rubish. Let';s call it what it is...starter disable. Follow the 1st diagram.

      thanks...so the postive door trigger i just dont use?  so i can just de pin it and take off the wire?  i'm trying to make it as clean as i can so i removing as much wires that i don't need.  
yea..i have a hoodpin that i'm going to wire up.  so that should be easy to do.  
for starter disable i just follow the first diagram in the instruction manual?  i just cut one wire going to the ignition, and cut the other starter?  for the integra it should be located near the main relay?
