So I was checking out my new truck and found this wire bundle under the hood. It's on the firewall near the Aux control box around the area of the brake booster. Does anyone know what these wires are for? I'm hoping perhaps like my old ford they had wires for things like speeding up the engine idle and others.
 
2021+ trucks with the AUX switches have 4 new "pass thru" wires. Four (4) of them are blunt cut. The original pass-thru circuit and one of the 5 new circuits are present in the upfitter jumpers.

Thanks for the info!! Sorry the picture I tried to upload didn't go through, I don't know why it didn't but I have a lot of trouble posting on here. Most likely it's me. lol
