I'm doing a 2v turbo swap on a 87 mustang . I'm wanting to use factory wiring out of 99-04 gt so I can tune it with sct.. not worried about the stock gauge cluster working as I'll be doing gauges eventually.. I did few searches and didn't seem to find anything.. what harness's from he gt do I need ? I need the obd2 port to work also ... thanks in advance . Sorry if it's been ask before I just wanna make sure before I go buying a harness I don't need..
