I want to hook up an alarm system that flashes the parking lights when locking or unlocking. I found the brown parking light wire for the lights in the engine compartment. If I tap into that wire will the rear parking lights also flash?
Thanks Dave

Easy test is to take a jumper from the battery to the brown wire.

I think it will though.

Thanks for the idea. I sent 12 volts to the wire and the front and rear parking lights lit up.
Thanks
