    Pretty much as the title suggests, when looking at the Vboost cable, which direction opens the butterflies? The cable moving towards the rear, or moving towards the front?

    I have found that I have not one, but two non-functional Vboost controllers. The one that came on my 86 is dead, and the one from an 85 I had in my spares bucket is dead. Lucky me. So for a while, I want to power the butterflies to the full open position and assess how it runs. Which way guys?

    Never mind. Thanks anyway. I figured it out. The cable moving forward opens the butterflies. Forgot I had a spare Vboost manifold on the shelf. Simple matter of eyeballing that thing.

    If you buy a momentary DPDT switch, you can use it to open and close the Vboost as you'd like.
    Unplug the power feed to your existing controller.
    Run a + and - wire from the connector to the switch input.
    I put an inline fuse on the + just in case.
    Cross the + and - wires over to the opposite pins of the switch for the second input.
    Output goes to the vboost motor.

    This file has the same info but there is a little wiring diagram @ the end for the switch.

    Dang. That's a pretty cool idea. I'm glad I thought of it.

    (Thanks!)
