im putting a remote start on my car and i can't figure out how to make the power lock function work... i have figured out that it needs a positive to trigger it, and the system i have outputs a negative, what do i do? the remote start system i have is a galaxy 2000-rs.

you will need two relays or see if you cant get you hand in one of this a 453T power door lock inverter it changes negative pulses to positive.

DEI DOOR LOCK VOLTAGE INVERTER - CONVERTS A NEGATIVE INPUT TO A POSITIVE 1 AMP OUTPUT. IDEAL FOR CHANGING AN ALARMS NEGATIVE DOOR LOCK OUTPUT TO A POSITIVE DOORLOCK OUTPUT. COMMONLY USED WITH GENERAL MOTOR FACTORY DOOR LOCKINGSYSTEMS
