Default External wastegate help needed!!

Ok just started the car with the new tubular manifold (it has a blow hole somewhere ) and ext wastegate setup and the wastegate leaks. i then realised i hadnt got the boost signal pipe connected (Doh!) but having jsut read the instructions that came with it, im confused. see pic of wastegate and pic of instructions.


if im reading these instructions right (and im probably not!) the bottom connection of the wastegate needs a 6mm bore feed from a boost pressure source BEFORE the throttle body. now that could be anywhere from the compressor housing takeoff all the way to the TB intake itself so long as its before the actual butterfly and not IN the inlet manifold itself?
If i wish to run at whatever boost level the wastegate is set at, i use a direct pipe and leave the top fitting open to atmosphere?
But if i wish to alter the boost level with a boost solenoid (i do...), then i 'T' off from the 6mm pipe to the bottom one, and put the boost solenoid between the 'T' and the top wastegate connector, yes?

sorry for being thick, but ive put around 80 hours into the car in the last week alone and the brains fried.
