I want to connect this oem siren that I purchased. I have a hard time finding which wire runs to the engine bay from the back seat where all the harnesses are at. Help Pls..... (The alarm/keyless entry is intact and working but I want to install the siren in place of the sound of the factory horn.) Thanks.
