parking lights on a 95 sebring

I'm installing a Audiovox APS-685 in my girlfriends car and I am about done,  but when I went to hook up the parking lights wire I tested it with the switch off and the wire showed 12 volts on the DMM.  The wireing diagram showed GRN/WHT+for the parking lights.  Did I hook up to the wrong wire?  I hooked it up to the GRN/WHT wire at the switch and the other wire to ground because there are 2 parking light wires that are hooked up to a common and the other to a normally open contacts of  a relay inside the module assusmeing that this should work.  What do you think?

If you are using the (-) trigger wire you will need a relay to reverse polarity.
