I recently installed a car alarm system for my civic but the double locking is not anymore triggering even pressing twice it wont budge! pls help

 

what system you installing. honda outputs are (-) trigger. you can test to see if they neg with a DMM (digital multimeter) if you confirm its the correct wire, add a jumper wire to it and touch it to ground. if you touch ground and it locks, you have the correct wire. also test the output of the unit and see if its working properly. you might have to use a relay to get a stronger pulse for the door locks, but i doubt it. this is because the lock/unlock wires you are tapping into is the lock module. you are simply powering the factory lock/unlock relay. please give me more info, like what unit and what you have wired in so far.
