Ext wg vacuum source?
First time using a ext WG so does it just get it's vacuum source like the same as an int wg? Straight from the compressor housing or just tap a vacuum line? Also what is the hole on the top of the WG for? Do I just leave this open or plug it?

not a vacuum line, a boost line. The wastegate opens when it sees boost, a bov opens when it sees vacuum.
WG=pre-throttle body line
BOV= post throttle body line
post pics of which hole you are talking about, or at least tell us which wg you have

I still don't understand why people still run theirs to the turbo compressor nipple. The wastegate will open earlier from hooking it up there because of the pressure drop across the intercooler. You want to hook it up after the intercooler. Most people i know hook theirs up to the intake manifold. Also just leave the top port open unless you have an EBC.

hook it up as close to the intake manifold as possible. i run mine from my brake booster line, between the intake manifold and the check valve above the brake booster. this is the second setup ive done like this with no problems
