Sending ground pulse

I have car remote starter and it has external trigger wire so if that wire is connected to car body (ground) than it starts the car and connecting again will turn off the car. I would like to use boron 404x to send ground pulse so wire coming from starter would connect to wire coming from car ground. I know I can use relay to make it happen but there any easy or another way without using relay?

You could use a FET (with current limiting resistor).

Do you have any link for parts and diagram please?

All I want make remote starter trigger wire touch to car ground with high low signal from boron.
