It will not hurt anything, but will produce that annoying buzz.

With your remote starter, can you select negative instead and wire to the negative wire instead? If not, you can use a standard automotive relay as an inverter:

I have two wires: 1) Parking Light Flasher Feed 2) Parking Light Flasher Output

I have 2 connected to the parking light switch wire under the column and 1 connected down there by that relay. The remote start manual says I can connect 1 to a standard 12V source for + switching and ground for - switching, so I guess I should put 1 to chasis.

Thanks for the clarification!

edit: Yeap, that worked. Thanks again for the clarification on the switching!
