Fitting pipercross induction

[chrisw1991]

started fitting a pipercross induction kit today and ran into a problem with hoses checked a few posts on here but not really solved anything i have a mk 1 vtr

this is what it looked like with stock air filter



pipe 2 is connected into 1 connector on the kit but i duno which pipe to put into the other connector or whether to put the sensor into that. Pipe 3 comes off the rocker cover and blows air out so does this need to be on the air filter or an air breather ? if not i could do away with this and then put the sensor into the induction and then put my breather filter onto pipe 4 but if not then a duno what to do with it any ideas ?
