2010 Sebring no backup lights
 

My Bride's 2010 Sebring Convertible(3.5l) has no back up lights. I check and have no power. The only diagram I can find is for a 2007 Sebring which show a relay in the TIPM as the power source. My issue is that the 2007 TIPM appears to be different that the 2010 TIPM. I want to put power to the wire feeding the backup lights before I spend $400.00 for a new TIPM. Anybody know which plug and wire at the TIPM feeds the backup lights? They 2007 TIPM claims it's a white wire with a Lt. Green tracer. I found two(2) white wires with green tracers and I don't want to just put power to a wire not knowing what I am feeding. Ya know - 50/50 - 90 Rule. I checked both grounds in the trunk and they are clean.

Have you checked the switch in the shift linkage?
