You say the the tow and non tow fans are not interchangeble - Is it connector and wiring related? I know about the relay difference (2) 40a vs (1) 60a I just bought a used edge that had a FOMCO hitch and trailer plug on it but the OEM window sticker did not say tow package. My mistake as I planned on towing 3000# I have verified its the 60 a non tow cooling. I would like to upgrade to complet the tow package.

ETIS does verify that is has "less towing" "less Sunroof" etc. My question now is can the tow fan be plugged in and just put in the required relays ?

I just got a CPO 2012 Edge SEL with 3.5L. The factory window sticker did not say tow package but it had a FOMOCO 3500# hitch and factory 4 pin connector on it. It looks like factory install from underneath but maybe it could have been added? It doesn't look like it was used at all. Factory hitch and connector Now I looked under the hood and big fuse box and found only the 60A relay with reference to the (2) 40A relays for TT. My fan assy is pn# 9T43-8C607-AB If i go to Rock auto they do show 2 different fans and 2 different radiators. The Tow fan RF-259 Motorcraft rad has PN #9T4Z 8C607A The Non tow fan RF 223 - has PN #7T4Z 8C607A I have looked at the Fan assy it is the no tow style ( 2 fans and one connector) I guess the easy solution is to add the Tow fan but I don't know if its plug and play and add the 40a relays
