everything i see is for negative outputs from an alarm. i believe i have positive outputs for both signals. how do i turn them into negative signals when wiring them into my single wire lock/unlock car? i have the wiring schematic but its for a negative input. wondering how i turn it from a positive from the alarm into a negative. any info would help. thnx

Use a relay
                                    __ (negative output)

                                    __

(+'ve from alarm) |             | (to earth)

                                    __ (to earth)
