Hi guys just got a new lorry and i was wondering if anyone knows where to get the connection bit for the air gun. there is an outlet already built in under the seat but it is smaller then the ones you have on the end of the air line. thanks
Get a T piece connector and connect it to your passenger seat, or even drivers seat.
ye you cant get in under the seat with out taking the whole lot out. its not like the old ones where you had the plastic thing that just popped off… our fitted had a look at it and its major effort getting into the seat
Can’t help you then bud, but mebbs some of the fitters on here will know.
cheers anyways robroy
I’m having the same problem, I’ve got the enclosed seats too…so don’t really know where to put the connector?
unscrew the plastic foot plate just inside door,you will find the air pipe to the seat,get a 6 mm adapter exrension.£5 from pops) cut pipe 
and push each end into extension and pour in some areldite to seal (other glues are available). feed extension to back of seat and carefully replace plastic cover.job done.
worked for me
daf air duster to fit that connection is £40 +vat
