89 Prelude, wiring an alarm

aite ready, all the colors and locations are off the top of my head so double check them

constant 12v- in the ignition harness-should be the thick white wire- should read around 12volts                              

ignition (switched 12v) in the ignition harness- should be the thick black with yellow stripe wire- will read around 12volts when you turn your key to the second click

starter-in the ignition harness-should be black with white stripe wire-cut it and then try to start you car, if it doesn't start, guess what thats the right wire

ground-ground it anywhere on the chassis

parking lights-go to the fuse box, i think right above the fuses are male terminal blades, I think it is the second from the left-it will read 12volts only when the parking lights are on

door trigger- driver kick panel-I cant remember, i think it is light green with a red stripe-hook up your multimeter's red probe to a constant 12 volt source and the black probe to the door trigger wire, shut all the doors and the multimeter shouldn't read anything, but once you open any of the doors it should read twelve volts- remember honda is a negative trigger so use the negative trigger from the alarm, not the positive.

door locks-driver kick panel again I cant remember the colors-the fastest and easiest way is to get a short piece of wire and connect it to a ground put a 1 amp fuse in line with the wire (very important, must not be bigger than a 1 amp fuse) then tap the other end of the wire to the lock or unlock wire on the vehicle. if the doors lock or unlock the those are the right wires.  Or you can use your multimeter basically hook it up like the door trigger but you press the lock or unlock switch on the driver door, depending on your multimeter it will say 12volts very shortly or it will just fluctuate for a short period when you push it, thats because the change in voltage is to fast for the multimeter to display it all

I think that all for a basic alarm install good luck rookie
