If your car already has power trunk release ( electric motor ) then all you will need is a relay, but if you do not have factory power trunk you will have to use a trunk release solenoid to pull the cable that releases the trunk latch. ------------- Jeff

The target wire is a BLACK/ WHITE at the trunk release switch. You will need to give this wire a momentary ( + ) signal. If your alarm / remote starter does not have a ( + ) output trunk release wire, you will need to install a relay that chages polarity. Wire up a relay like this: - 86 + 87 - 12 Volts Constant
- 85 - trunk release wire form alarm or remote starter
- 30 - BLACK/ WHITE trunk release wire of Grand Prix

Hey, I have a question. If you need to get a solenoid, do you still need to get a relay? Also... My alarm has a ( - ) accessory output. Can I just hook that output wire to the positive wire on the trunk release solenoid? thanks,

Hi AcuraRacing, yes, you still need a relay. Connect the (-) accessory output to #85, connect 12V+ to #86 and #87, and connect #30 to the positive lead of the solenoid. the12volt

If you need a solenoid you still would need a relay to activate the solenoid ( most solenoids require more amperage than the alarm is capable of outputting. You can not feed a (-) signal to a positive input device.... you will fry the device or even worse you will fry the alarm unit. You have to convert the signal to reverse the polarity and it will work fine. ------------- Jeff
