Im not sure if it was an original equipment install. I do have a vacuum line that is connected to the passenger side of the tranny and runs directly from the manifold. Since PO replaced original 4 bbl carb with Holley and did not hook up this switch, my assumption is that I don't need it anymore, right? Assuming I do not need this switch anymore, then I'm wondering if the red wire connected from the switch to the tranny is necessary. Can anyone shed some light?

PS - I'm getting ready to do a complete re-wire and I'm trying to sort out what's old, what's new etc..
