Don't rush to buy parts - check the connector at the VSS first - I'd probably check the VSS by removing and spinning with a rotary device.

With the SRC and the cluster out it's certainly VSS or the circuit I'd think. If you still have the Delco Bose - does the SCV still work? That would be very unusual and would certainly I think complicate diagnostics. If you had a scanner and it worked then it would certainly create diagnostic issues.

Clean and check connector to the VSS first - remove VSS and spin with rotary device. Get your self a seal GM# 15552872 so you can reseal the VSS when going back together if you remove it. It should be on all dealers shelves.
