last time tried before...but failed....first time i tapped on the signal light connected to alarm module, turn out the UCL blinking when i put signal also, when turn ON the UCL and signal light remain constantly ON also. Second time tapped from siren module, using relay. Suppose to trigger the UCL when the siren go off and no to trigger siren when i ON the UCL. But it didn't work out as i wish, i think i didn't wire the relay correctly lo, altot i tried many ways already...sigh
