Blow Off Instalation Problem

[Guest Robo's]

Im installing back my BOV for something to do, its a HKS one, now theres 2 pipes coming off it, one smaller and the other larger, one is t pieced which runs to the hose going to the canister, the other one i dont know, so i joined it all up and blocked the end off.

Went for a drive last night and the noises are right, but the midrange performance is crap, it surges around. Took if off and no problems.

Has anyone got a diagram of where those 2 connectors go???

Ive just seen a picture, i had it right, must be another problem.

Is it a plum back one?

If not your car will be running rich on gear changes...
