Question:
Im not sure if this is something you guys can help me with or not. Im trying to figure out what I need to wire up my vehicle. I have a 2012 Chevy Express 2500. I would like to wire it up for a 7way and 4 flat plug. I would ideally like to add a brake controller in the future as well. I just cant for the life of me figure out what harness I need. Here is the vin as well if thats any help. 1GCWGFFA8C1146413.

Hey David, we can definitely help with that! So the first thing you need is a 4-way like the part # 118392 that is a confirmed fit for your 2012 Chevy Express 2500 and then from there you'd need to convert it to a 7-way with the part # ETBC7 which comes with everything needed to wire in a brake controller as well like the P2 part # 90885.
The ETBC7 kit has a 4-way on the side as well so you'll end up with both connectors you are wanting as well.
