Wish I could help, just started researching this myself. I take it you did not have any issues installing your FF harness?
I just switched to map 2 without the EWG and FF which will limit my peak boost so I might pick up 1psi 8-12 whp. If I don't feel a difference I will roll back to map 1 and contemplate ordering the EWG and FF for this install which looks to be a PIA due to location and access.
Time for my first test spin on map 2
