Impulse-990 Alarm/Remote Start, 2000 Cavalier Z24

The ORANGE wire is an optional connection taht you only have to use if you have a device that you wish to operate after you arm the system ( window modules for example ). The dome light supervision leaves the dome light on for about 30 seconds and then shuts off.

One last question about the relay switches for the door locks, I was at my local Canadian tire store today and they had relay switches for fog lights. They looked exactly like the ones on this site, with the number's 30,85,86,87,87A it was 30 amps, 12volts do these sound good enough?  cause they were only $6.

And can anyone suggest a simple but cheap bypass for the passlock II

Thanks again

$ 6.00 !!! I wish someone would pay me that much for the ones that I sell  Try this:

This is an ongoing project!  Thanks for that pic it's HUGE!  but I am confident it will be helpful.  First of all those three wires are they thin? they are not the ignition wires right?

One wire says "TO GROUND WHEN RUNNING FROM CAR STARTER (-)" is there one wire from the alarm/starter that I should connect to this, or do I just ground it?  If so that means 86, 87 & 30 on the left relay are  grounded with 86 on right relay? correct?  Bare with me here for hoepfully one last question...."TO VEHICLE'S IGNITION WIRE" which side of the wire would that be? the side going to the key or  to the starter? as my ign wire is cut in two thru the alarms internal starter bypass  

Thanks for your patience

Here is the wiring for my alarm (about 1/2 ay down the page) http://www.internationalelect.com/mantis7.htm

Sorry about the picture size, forgot to resize the scan before I entered it into the data base ( my bad  ) The 3 small wires will be about 20 - 24 guage in size ( really thin and NOT the ignition wires ) . The only problem with the IMP 990 is that there is no GROUND OUT WHEN RUNNING wire available. The ground when armed wire does not do the same thing as this wire will ground the all the time when the system is armed ( not what you want ). What you will have to do is use another relay to convert the ( + ) ignition wire to a negative signal to act as the GROUND OUT WHEN RUNNING wire. Wire another relay in this configuration:

• 86 + 87 : GROUND
• 85 : Ignition wire from car
• 30 - This will now be your GROUND OUT WHEN RUNNING wire

Make sure you diode isolate like it shows on the diagram to ensure that there is no feedback signal going back into the wire.

The IGNITION wire you will just tap into. You will not need to cut this wire at all. Use this wire also in the above relay to convert the signal to a negative output. The only wire you will need to cut in half is the 22-24 guage YELLOW wire for the Passlock II bypass.

Please confirm 86 goes to GROUND and to IGNITION WIRE??????

86 + 87 GROUND

86 TO IGNITION WIRE

30 BECOMES GROUND OUT WHEN RUNNING wire

Sorry !! Got ahead of myself there. 85 is the ignition wire. I will correct it above.

The pic you sent about bypassing passlock II https://www.the12volt.com/uploads/files/Passloack_II.gif  has left me with yet another question......

When I measured the resistance from the yellow (ignition side) and black I got 1.755 then I switched the leads and got 1.795, after doing it all over again I still  got 1.755 and 1.795.  Does that sound right?  1.755 ohms? What size resistor would you recomend? 

Either one would be good. The resistance difference is less than 1 % and your allowable range of error is 5 %. You can use a resistor any where from the range of 1.667 to 1.885, but try to be as close to the resistor value that you have as possible for trouble free bypassing.

hi exit69

i have the excact same alarm ai probably bought it from the exact same seller too, i was really disappointed by the instructions. i also have that problem w/ the ignition actually turning on, then turning off again. for some reason, it worked fine for me for about 2 day, and i open up again to mess with it, and now its doing it again (its starting then turning off) my car has worked before, so i don't know why i stopped working. please let me know if you find out how to fix it i have a 98 honda civic. thank you
