It runs from the ecu to the cluster. I believe its the white and blue wire.12 cbr250r: daily ride

its triggered by the ecu. I think its based on the air flow meter position.12 cbr250r: daily ride

There's a boost sensor... somewhere. I'll have to bust out the FSM and see if I can find it. It should come on at roughly 5psi.
EDIT: Ok I can't find my FSM. I'm in a hotel room and haven't transferred it onto the laptop. Anyone else have one, or remember where it is?

I know the capri has one but I don't think 323s have a boost sensor other than the overboost switch.12 cbr250r: daily ride

Thanks I remembered what it looked like but for the life of me couldn't remember where the hell it was.

On the firewall there is a vacume block where a bunch of vac lines go, right off of that there is a hose that goes to a little black thing which kinda looks like a UFO and that is the pressure sensor for boost and overboost. i am pointing at the pressure sensor in the pic.

It says pressure SWITCH which is overboost switch. I have that disconnected on my gt and boost gauge/light still functions the same.12 cbr250r: daily ride

I bet you disconnected the harness not the vac lines.

Shorestiva- disconnecting the harness from that switch is what most people do so they don't get the annoying overboost buzzer."See that car, in the 80's that car was deadly." Random man to his son while passing the GTX in a parking lot
