It was much easier than I thought. Bought this wiring harness from eBay:
http://m.ebay.com/itm/2X-NEW-9007-HB5-Male-Wire-Connector-Wiring-Harness-Pigtail-plug-socket-adapter-/380926454774
Then cut the connector off of the GT headlights and wired the harness on. Black to black. Left red on eBay harness to red. Right red on eBay harness to green.
