CAMARO6 - View Single Post - 2016 SS Dash Harness Swap into 2016 1LT V6

Hey guys, long time lurker here. I have a 2016 1LT V6 (IOB radio) that I'm doing a phased ZL1 conversion on over the next few years.

My immediate goal is to upgrade from the IOB 7" radio to the IO6 8" MyLink 2.5 system. I understand the IOB is a completely different architecture from the IO6 and the wiring isn't there in my car to support a direct HMI module swap.

My plan is to source a complete 2016-2018 SS dash harness from a salvage yard to solve the wiring problem, then drop in a used IO6 HMI module and display.

My questions:

1. Will a 2016 SS dash harness physically fit and mate correctly to the existing body harness in my 1LT? I understand the body/dash structure is identical across trims.

2. The SS harness will have connectors for hardware I don't have yet (memory seats, different HVAC controls, etc.) - will those unplugged connectors cause any DTCs or module issues?

3. Has anyone done this specific swap - SS harness into a base 1LT? Any gotchas I should know about?

For context my long term goal is a full ZL1 conversion so the SS harness makes sense as a foundation for everything else coming down the road (memory seats, upgraded cluster, etc.)

Thanks in advance.
