Lighting Module Plug Identification and Pinout

Greetings!

Looking for some assistance......can anyone tell me what color plug X5 is on the lighting module and the pinout of X5 as well? The lighting module has 5 colored plugs and I need to access PIN 25 on plug X5. See diagram I found online (red circle).

Why you ask? I want to install a 3rd brake light flasher and trying to see if it would be easier to access this plug than removing the rear bumper so I can wire a flasher module in series on the output of PIN 25.

Thanks in advance!

Not that I expect it to be different, but what year and model?

Oh dang, forgot to mention that rather relevant piece of info.......it is a 2026 Z06 HTC. But I agree, I doubt it is different.

If I'm reading this correctly, X5 is a blue and gray connector.

CHMSL supply voltage is pin 25, which should be a Brown/Yellow wire.

Looks like there's an ignition hot wire on pin 18, should be a Violet/Black wire (in case you need that for module power).

It does not look like there is a ground in this connector.
