Usually that goes to an aftermarket wastegate. Thats the place I see them most commonly run. Someone must've decided to go internally gated on that GT40.

yeah, i finally found a diagram from tial that shows it going from the housing to the TOP of the wastegate.

Thats kinda what I figured. My 38mm TiAL sport was setup the same way. GL with this.
