Does this house have two layers of lap siding? Or is the inside layer square-edged boards laid against each other (not overlapped) – perhaps on the diagonal? This was a common way of sheathing a house before the advent of plywood. Sounds like removing the old siding might be a good idea – certainly would make replacing the old wiring in the walls easier. Having replaced the wiring in a 57-year Tyvek is not a moisture barrier – it is an infiltration barrier applied outside of the insulation and sheathing and under the exterior wall covering (lap siding, brick, etc.) If you put batt insulation in, it would have a built-in vapor barrier (kraft paper) which would be installed against the inner wall.
