I feel like i need to tell people about my experience trying to install the Curt wiring harness on my 08 fx35. It is complete madness! I had this long post that i was gonna vent on and serve as a warning to try to keep others from going through the same headache that i went through, but I am just gonna summarize because im sick of even thinking about it; Just buy the oem wiring harness from the dealer. There is misinformation out there about Curt harness and after spending hrs calling curt and troubleshooting, it's just not worth it. The correct Curt part # for 06-08 fx35 is 56201 if you want to go that route but i cant verify that it actually works.
