right i'm fitting an external wastegate and turbo to my escort when i get around to building it

the wastegate and manifold etc all came from a car that reyland built
it was all plumbed in and working
but its been lying arounf now for a while and i cant remember how thew vac pipes all go
the external wastegate itself had 2 pipes going into it, and the turbo has 1,
it did not run with a boost controller, it was just piped in thru the amal valve somehow using 2 bleedvalves,
any help/diagrams or information on this would be great as i've drawn a blank with it,
i should have made a diagram when i stripped it

i did ask martin a while ago but never got a reply,
i know he's a busy guy so i dont want to keep annoying him
