Seems I have a habit of not plugging things in....

But this is the back of my SRS ECU and it looks like I'm "unplugged"?

There's nothing left to plug into it, what gives?

SRS light goes out as normal after ignition on... no other errors.

The J-series SRS ECU is a twin plug type, however only one is used. I think the other may be for side airbags?

Phew!

Good to know, thanks.
