Installing alarm

[C-max]

good day

I bought alarm system that i have installed in my 2007 Yaris. What i wanted from this was to be able to lock and unlock the doors using the remote, it has a lock/unlock button between the driver and passenger seat just next to the handbrake lever. i managed to tap into the switch wires, it locks and unlocks using the remote but now the switch no longer works and i like to lock my doors wen am driving. now it requires me to arm the alarm to be able to lock the doors and since i will be inside driving the alarm will go off and i also taped in to the driver door switch wire to set the alarm off but the passenger door doesn't set the alarm off . Now my head lamp indicator on the dashboard not working and also when I open door with the lamps on there is no buzzing sound. I need to no where to tap wires to get my indicators flashing when arming or disarming the alarm. pleeeeaaase hlp am scared to tap any more wires
