Hi... My first post.

I have a 2016 Honda Fit that is having an issue well-described in youtube videos (flickering lights all over the dash, alarm coming on a random, clicking relays, etc.). I know the key fob is okay, and has fresh batteries, and I have found info that the circuit board for the Smart PCU is a likely culprit, with some touch up work on the board the fix. I work on hifi equipment for my job, so I am up to the task of taking a look. Problem is, I cannot find the unit! I removed right side of the dash and the glove box because I had read that it is likely there, but it is not. Just air flow unit and motor. I can't find any service docs, except a photo of the unit on the Honda parts site, but the diagram isn't clear about where the unit is in the car.

Hoping someone can help me locate this unit! I'd be grateful.

Thanks.
