Installing a Boost Command BSTC controller need a lil help

[Dhos1]

After the install how do I reroute these turbo lines after I remove the manual one. Also, what is this wastegate splitter for and where does it go?

The BSTC works with the stock style wastegate plumbing excepting if you wish to add two solenoids then you install them in parallel so they both bleed at the same time.

Find a good stock gray Y with the right sized hole and plumb it all stock.

You can use a simple T fitting to parallel two solenoids which will increase the control some, works better in MHO with the heavy duty spring actuators.

Got it all hooked up but have a last wiring question? Look at the picture where circled in red. See where the instructions say: To Bsct C white and Brown m/f. The white one goes to the purple and white (solenoid) of the vehicle harness, and the Brown goes to the boost control Purple and white also D3. Are they the same wire? I can identify the D3 obviously, but how do I find the other one

Yes it's the same wire. The BSTC goes in between the ECM and the Wastegate Solenoid.

When you cut the wire you now have two tie points, make sure the ECM end goes to the right brown wire, solenoid end to the white wire.
