Confused by Amp install

[Kinamyen]

I have a 2020 Laramie with the the Alpine system. I have speakers and amp and I bought :

PAC APSUB-CH41 AmpPRO SUB Advanced Amplifier Interface for Select 2013 to 2020 Chrysler, Ram, Jeep, and Dodge​

and

PAC ANC-CH01 ANC-CH01 Factory ANC Module Bypass Harness for Select Chrysler, Jeep, and Ram Vehicles​

because it said I would need it. When I took the radio out today there is not the big harness. Just looks like this: So can I just use a regular LOC? Do I need the ANC?

Guessing you figured this out. That big silver thing in your photo is the main module for the stereo. The T harness is behind that.

 

[woojyee]

The plugs are behind that, remove it and you will see them. Second, you have an AMP and not the ANC so do not use the CH01.
