they come with a 3mm fitting tapped into each one, i tapped another bigger fitting for the brake booster vaccume, also as a bit of a balance tube to help idling.. (use to work with webbers etc, this does wonders for idle!)
t piece etc the all in.. use the 3mm one for the map line.. and the bigger one for the booster.. try and balance the qauds as best you can befor you put them on, cos there a bit of a bitch once there on.. if they come off a perfectly running 20V don't touch the idle screws..
i made up a cable bracket, although the cable on has a bit of slack, it's enough..also it's the stock 4age ae86 cable.. i made the 4age 16v tps switch fit as i didn't have a 20v one.. i made it fit buy using the 20v gold metal bit thing, bending carefully the tabs 180deg 'backwards' and she all fit beautiful..
