Hi all,

I have a three-wire (Hot/Light/Ground) brake attention module (makes brakes flash fast when first pressed) that I want to add to a 2019 GX 460. Can anyone point me to a wiring diagram for the brake light switch harness?

Thanks for the link. Unfortunately that concerns automatic lane changing signals. I’m referring to an add-on that makes brakes flash rapidly momentarily before going solid. So I’m looking to know which two wires in the brake switch harness are hot and brake light feed.

I thought about adding one of those. Theres also a version that measures G's and does some other stuff when the brakes get slammed.
For most cars, there's usually a switch at the pedal.
It looks like there's a few places you could insert the module.
Note that this might be different for different years.
