Kr overrun valve set up

does anybody have a pic of the over run valve set up. For a kr as I think I have the wrong set up. Just trying to get it right as I have a big pipe coming off the inlet and not a small vacuum pipe, pic will help  and does this wire go to it

that plug goes to the small metal valve on the back of the airbox, its the throttle enrichment valve.

the over-run valve is bigger and plastic, with yellow/black and brown/black wire. it should be connected between a pipe on the rear of the airbox and the rubber boot or plastic pipe, depending on the combo of mk2 bits yopu got as they changed in 1990.

note the over-ruin will only work if you have wired in the isv control unit
