Ok so I appreciate everyones thoughts here. After more research I found that the 370z will not work. The bolt patterns are different for the wheel lugs so that's dead.    The good news about this is I found out for sure you can swap the brake dust shield from a 2023, 2024 edge or the same part number for the edge st performance brake package (same brake dust shield). After that it was just throw the standard rear vented rotors from the 2023/2024 edge and pads on. The calipers are the exact part number, the pads are the same dimensions just a different part number. The standard rear vented rotors have the same hat height as the stock inverted vent style so, it's all bolt on and go. Feasibly this is the best and cheapest upgrade for the edge brake system if you don't have the st performance brake package. This is essentially a way to upgrade to that package and the only additional cost (if you needed rotors and pads anyways) would be the dust shields.    In the end I told my buddy at advance auto just sell me the rotors and pads for a 2023 edge and it spit out the part numbers I listed below. I ended up going with the high carbon rotors and platinum brake pads. I have yet to do any high speed stopping (what warped my rotors last time) but, I imagine the improved rear vented front rotors will be a huge improvement over the stock front vented rotors. I appreciate everyones input on this subject.   K2GZ-2K005-A - front left dust shield. K2GZ-2K004-A - front right dust shield. AR85200 - powestop oe replacemnet brake rotor Yh78111hc - carquest high carbon rotor Pxd2427H - carquest platinum brake pads.  

ok

As you're responding to a thread more than seven years old, it's unlikely you'll get an answer. 

Did you try to unplug the connector from the Gateway and try to plug it into the other end of the T-Harness, the side not shown in your picture?   Even through the plugs look different from the outside, the the one on the T-Harness being straight and the vehicle's sideways (or L-shaped), from online photos, the actual connectors look to be the same and probably should plug in. 

thank you so much for this right up had to use google to find it. forum search did not bring this to me.  have you got the retrofit fog light switch? 

I had time to dig into it tonight. Sadly, the main harness doesn’t have the correct size plug.  Anyone else have an idea where the correct gateway is located?      

And Model? - Part Number ?   Have you measured the resistance/continuity of the heaters and confirmed voltage across them?

Oh my, right rear quarter panel. Quite a ways from the OBD2 plug. Are we talking about the same gateway?  I will take the carpet down on Sunday to look for it.  I have a 8 hour drive home tomorrow then a wedding on Saturday.    

The gateway location apparently was moved. Check page 17 in the installation manual here: https://www.fordservicecontent.com/Ford_Content/Catalog/accessory_files/2021_RMST_Common_I_sheet_11_5_20_D1_002.pdf
