Jake's Black Box/SloppyMechanics Transbrake Have a built 4L80 using Jake's Black Box for the Manual Valve Body. How would I go about wiring this since I am not using the PCM controls.

Same way. All you're doing is grounding the 2-3 solenoid and forcing the trans into 3rd gear.
Find a google image for the 4l80e trans harness connector...identify the wire you need...tap it...ground it.
I'm 90% sure this will work, but I've never been inside one of jakes Black Boxes to know if you will have any back-feed issues that may trouble the box...best thing to do is call them and ask.
