I didn't buy the  curt harness and only bought the oem I listed that never did work. 
 
Journeyman says the 4 pin should work but the dealer says only the 7 pin will work. I have the 4 pin which doesn't work after the flash was done. 
 
If if you want to cover shipping I'll send you the 4 pin if you want to try it out and if it works we can work something out.
 
i wanted the oem harness since it adds anti sway when using it and it's clean without tapping into anything.
